Balancing Multiplayer Games, Part 4: Intuition

We’re in much deeper trouble than I’ve been letting on when it comes to balancing games. The problem is that you cannot solve your game--you definitely cannot--yet you must somehow balance it.

By solving, I mean you cannot determine how to play your game optimally. If you could determine this, there would be no actual strategy left in your game, so it would be boring and not worth talking about in the first place. If you can solve your game, your players can definitely solve it. If you can’t solve your game, your players might still solve it. In any case, we know you can’t solve it because that means you did a bad job designing it in the first place.

How in the world can you balance something when it’s impossible to know the best ways of playing it? If you aren’t worried about this, then you don’t understand how wicked the problem is. The techniques I discussed in the previous three articles will help, but they remind me of what art director Larry Ahern said when he was preparing to draw all the backgrounds in The Curse of Monkey Island. He said that by following the rules of composition from classical painting, he believed he could get results that were "not terrible." But, he said, going from not terrible to great was something he hoped he had within him, and that it's not exactly possible to get there by following someone else's cookbook of rules.

Picking The Top Players

Let’s back up to an easier problem. Imagine I gave you a room full of players of a certain game and I asked you to determine who the best player is, and who is second best. How would you do it? Answer: you would have them all play each other.

What if I don’t let anyone play the game, though? I’ll let you interview the players or have them submit written answers to your questions about how they will play the game and what they know about the game. Can you determine the best players from this method? I bet you will do only slightly better than monkeys throwing darts to determine the answer. In all my experience running and competing in tournaments, I can say with some authority that there is little correlation between ability to win and ability to explain yourself.

Why are the best players not necessarily able to reveal themselves as best through interviews or speaking? I claim there are two reasons:

1) Spoken and written answers have extremely narrow bandwidth.
2) It’s impossible to access many of our own skills with conscious thought.

Both of these ideas have to do with the concept of the mental iceberg.

The Mental Iceberg

Imagine an iceberg that represents your total knowledge, skill, and ability at something, for example in playing a certain competitive game. The small part of the iceberg above the waterline is what you have direct conscious access to; it’s what you can explain. The gigantic underbelly of the iceberg is the part you do not have direct access to, and yet it accounts for far more of your overall skill than the exposed tip. When we interview players or ask them for written answers about how they might play, we are only accessing the tip. If one player’s iceberg has a larger tip (he tells a better story about how he will win), it’s entirely possible that his hidden below-water iceberg is much smaller than another player’s, and that’s really what matters.

The tippy-top part represents what you can explain or consciously understand. The huge underside represents your vast unconscious.

Narrow bandwidth

The amount of information you can convey in a written or spoken answer is actually very small compared the storehouse of knowledge and decisions rules you have stored in your head. Also, spoken and written language encourage linear thinking, while your actual decision-making might be a more complex weighting of many different interconnected factors. In a written answer, a player might say “move A beats move B, so I will concentrate on using move A in this match.” But really it might depend on many factors: the timing of move A, the distancing, the relative hit points of the characters, the mental state of the opponent, and so on. Players cannot communicate these nuances in an explanation the way they can enact them during actual gameplay.

No Direct Access to Parts of Our Own Minds

This concept might be hard to swallow at first, but it should be incredibly obvious if you think about it for a moment. You are not conscious of how your digestive system works. You do not have direct access to how your cells make and break the bonds of ATP and ADP to give your body energy. When you see a frisbee travel across the sky, you are not aware that your eye moves in a particular pattern of jerky movement that’s common in all humans (you believe that you smoothly follow the moving object).

One study estimates that the human brain takes in about 11,000,000 pieces of information per second through the five senses, yet the most liberal estimates say that we can fit at most 40 pieces of information in conscious memory. There is A LOT going on behind the scenes, and we do not have conscious access to it, even though we are still able to make decisions that leverage all that information. (Wilson, p.24.)

Blindsight

This is what blindsight looks like.The medical condition of blindsight is a particularly telling example. Blindsight is blindness that results from having damage to a certain part of your visual cortex. There are actually two different neural pathways for vision, and people with blindsight have only one of these pathways blocked. The result is that they are blind, meaning specifically that they don’t consciously experience seeing. Even though they claim to see black, they can still make decisions based on eyesight. In one experiment with a blindsight subject named DB, experimenters showed him a circle with either vertical or horizontal black and white stripes. Even though he can’t see so he has no idea whehter the stripes are horizontal or vertical, and sometimes become agitated when asked to guess, his “guesses” were correct between 90 and 95 percent of the time. In other words, people with blindsight can perceive the world more accurately than their conscious minds can explain. (Blackthorne, p.263.)

Instant Decisions

Another clue to this concept lies in decisions that we make extremely quickly. Consciousness does not coalesce instantly; it takes somewhere between 0.3 to 0.5 seconds to form. I know that that sentence is highly controversial amongst brain researchers, but I think it’s generally safe to say in times shorter than that, we have not yet formed enough of an awareness about what’s happening to be conscious of it. And yet, experiments show that we make decisions based on outside stimulus faster than this. For example, when people are asked to grab wooden rods as they light up a certain color, and the experimenter cleverly lights up one rod, then as you are reaching for it, darkens that rod and lights up a different one, he can measure when your hand made the course correction to go for the newly-lit rod. The course correction occurs almost immediately, much faster than 0.3 seconds, and yet the subjects believe they course correct only at the last moment, after 0.5 seconds. In fact, they don't even consciously percieve that the lights on the rods changed until after they made the course correction! They are making decisions before they are conscious of what is going on.

Tennis is more real-world example of this. Tennis pros can serve the ball at 130mph, and the distance between baselines is 78 feet. That means it takes 0.41 seconds for the ball to reach the opponent. New York Times writer David Foster Wallace said:

The upshot is that pro tennis involves intervals of time too brief for deliberate action. Temporally, we’re more in the operative range of reflexes, purely physical reactions that bypass conscious thought. And yet an effective return of serve depends on a large set of decisions and physical adjustments that are a whole lot more involved and intentional than blinking, jumping when startled, etc. (New York Times.)

Tennis pro Roger Federer has explained in interviews that he doesn’t like to be called a genius at the game, because he doesn’t think during the incredible moments when he returns balls few other players can. He acts before he is conscious of the situation by leveraging his unconscious skills.

Heuristics We Use But Can't Explain

Baseball gives us another important example. How do fielders catch fly balls? It seems like a very complex math problem with variables for speed, trajectory, gravity, friction from air resistance, wind influence, etc. Should fielders run as quickly as they can to the general location where the ball will land, then make adjustments as they solve these equations somehow?

No. The best way to catch a fly ball is to use the gaze heuristic, as described in the book Gut Instincts. The method is to look at the ball, start running, and adjust your running speed so that the angle of your gaze remains constant. You will then reach the ball just as it lands, and you’ll be in the right place. Experimenters found that the best professional baseball players use this method (and so do dogs), but that most of the players don’t know that they use it, and are unable to explain any method they use to catch fly balls. (Gigerenzer, p.10.)

This example shows that it’s very possible for the correct answer to be hidden in your mental iceberg’s underbelly, but it’s not necessarily a representative example. I chose it on purpose because the underlying decision process can be simply described, which allows me to describe it to you. But what if they underlying decision process relies on a complex weighting of variables that isn’t easy to describe? This is another clue that explanations of how to solve complex problems are just tips of the iceberg, and not necessarily accurate.

Before we get back to solving our near-impossible task of balancing a game that we can’t possibly know how to play optimally, I’d like us to look at two cases outside of games where experts solved very difficult problems. The different methods they used are extremely applicable our problem, and to solving any other highly complex problem.

The Case of the Greek Statue

From an example in the book Blink, the Getty Museum of California was considering purchasing a 2,600-year-old Greek statue for almost $10 million. To determine if it was a fake, the museum had its lawyers investigate the paper trail of the statue’s ownership and whereabouts over the last several decades and had a geologist named Margolis

...analyze the material composition of the statue. The geologist extracted a 1cm by 2cm sample from the statue analyzed it using an electron microscope, electron microprobe, mass spectrometry, X-ray diffraction, and X-ray fluorescence. The statue was made of dolomite marble from the island of Thasos, Margolis concluded, and the surface of the statue was covered by a thin layer of calcite -- which was significant, Margolis told the Getty, because dolomite can turn into calcite only over the course of hundreds, if not thousands, of years.

The statue in question.After 14 months of analysis by the lawyers and scientists, the Getty was ready to buy the statue. And then the trouble started. When the Getty was nearing the unveiling of the statue, a few art experts saw it and each of them had an immediate reaction that something was wrong. They didn’t know what, but they thought it was a fake.

One of those experts was Thomas Hoving, the former director of the Metropolitan Museum of Art in New York. When Hoving saw the statue, the first word that popped into his head was “fresh,” which he thought was an odd word to describe a statue that’s thousands of years old.

The Getty was worried, so they shipped the statue to Athens where they invited art experts to a symposium to look at the statue. Most of them said it was fake, too. “It’s the fingernails” or “it’s the hands” or “statues don’t come out of the ground looking quite like that,” people said. They didn’t know just why, but they knew. Then the Getty’s lawyers discovered that some of the statue’s ownership documents had been faked. The geologist (who was so proud of his examination that he wrote an article about it in Scientific American) discovered that it was possible to convert dolomite to calcite in just a few months using potato mold.

How did Thomas Hoving know something instantly that the lawyers and scientists could not discover after 14 months of investigation? He knew because he had an enormous mental iceberg of knowledge and expertise in this exact area. He dug up statues himself in Sicily. He also said:

“In my second year working at the Met, I had the good luck of having this European curator come over and go through virtually everything with me. We spent evening after evening taking things out of cases and putting them on the table. We were down in the storerooms. There were thousands of things. I mean, we were there every night until ten o’clock, and it wasn’t just a routine glance. It was really poring and poring and poring over things.”

The lawyers and scientists had a large “iceberg tip” in this case. They had lots of explanations why the statues were real. But if there’s anyone in the world who has a tiny iceberg underbelly when it comes to knowledge about Greek statues, it’s laywers and scientists. Hoving’s iceberg tip was small (he just had a feeling), yet his iceberg underside was enormous. (Gladwell, pgs.3-11,184.)

Thomas Hoving knows statues.Can you imagine trying to detect fake statues by asking Hoving to give you a theory of fake statue detection? What if his theory left out lots of things he unknowingly uses to solve the problem? What if his theory is actually wrong, and doesn’t reflect his methods at all (because he doesn’t know them himself)? That’s the inherent problem with requiring that any expert synthesize a theory of his own expertise.

The way to solve a complex problem is to develop an enormous iceberg underside. Is that just saying that you need “experience,” though? Experience is kind of a dirty word to me. George Bush has “experience” as a president and with foreign affairs. Do you want him running the country (or anything else)? Meanwhile Lincoln had hardly any experience. Experience is only as good as the person who has it, and even besides that, we usually use completely the wrong scale to measure experience.

If you have the experience of “shipping 10 games,” for example, that’s great but it doesn’t have anything to do with the particular type of experience--the particular iceberg of knowledge--that is involved with balancing a complex asymmetric game. Before we try to develop this iceberg, let’s look at one more example.

The Case of the Space Shuttle Disaster

Imagine that your problem is that you must determine how and why the Space Shuttle Challenger crashed. You are on the investigative committee, looking for this answer. What is the best way to solve this problem? Is it to be an extreme expert in aerospace engineering? Is it to be an expert at investigating disasters? The answer is to first live the life of Richard Feynman, then solve the problem.

Feynman is one of the most brilliant people who ever lived, and he demonstrated his ability to solve complex problems in many fields outside of his own field of physics. Feynman was not an engineer, but the shuttle problem required an engineering analysis. He was a fish out of water on the investigative committee, and had no experience doing anything like that. What he did have experience doing was analyzing problems in general. Taking in vast amounts of information, organizing it in his head, figuring out what mattered and what didn’t.

Feynman dramatically reveals why the Challenger crashed with a glass of ice water and rubber.Feynman took nothing at face value, ignored the rules of the committee, questioned everyone he could, ignored authority figures and the politics of the investigation, and instead focused getting real information. His very first interview was a marathon session with the engineers who designed the shuttle’s rockets. They had the iceberg of knowledge he needed and he knew how to get at least a piece of it out of their heads and into his own. By ignoring illusions like who had important titles or who supposedly knew anything and instead focusing on who actually had the relevant icebergs of knoweldge, Feynman--and no one else on the commission--discovered that the real problem with the shuttle was lack of resilience of the rubber O-rings during cold weather. (Feynman, pgs.113-153.)

If you are going to solve a complex problem, the two best ways are to be like Hoving or to be like Feynman. When I worked on Street Fighter, I was like Hoving. I have a mountain of knowledge about that particular game, so my expert opinion, even if it expresses itself as just a feeling, is worth a lot. On other games I worked on such as Kongai and Yomi, I was more like Feynman. I know how to solve balance problems in general, but there are playtesters who have bigger icebergs of knowledge about how to play the game at an expert level than I do, so I question them, watch them, and rely on them.

Developing the Iceberg

How do you actually get the iceberg of knowledge in the realm of balancing competitive games? Ideally, you want the Feynman-type of ability that can be applied to many types of problems, not just a very narrow domain of one game.

The problem with developing this type of knowledge is time. If we are instead trying to become expert players (rather than expert game balancers), we have access to a very fast feedback loop. Play the game against people better than us, see what worked and didn’t, adjust, play again. A game of Street Fighter takes only a couple minutes, and even an RTS game takes less than 1 hour. But creating a game and seeing how its balance turns out takes years. It’s a very slow feedback loop, and extremely few people get to even participate in it directly.

I think that there is a way to gain the necessary knowledge though. Here are the games I studied:

1) Street Fighter. I know about more than 20 versions of this game.
2) Virtua Fighter. It says version 5 on the box of the latest one, but really, there have been at least 15 versions of this game if you look closely.
3) Guilty Gear. I know of 8 versions of this game.
4) Magic: The Gathering. This game has changed (with new sets of cards) about 3 times per year for over 10 years.
5) World of Warcraft. I played that game for two years before it was released and I couldn’t even guess the number of mini-releases over that time. Maybe 50 or 100.

That is A LOT of data about how changes to a game’s balance out. You can study what the exact changes are from one version of a game to the next, then learn how those changes actually affected the game’s balance and how they players perceived the changes. I actually count those as two separate things, and on Street Fighter I had two separate main advisors: one who knew the most about how a change would affect the game system itself, and another who knew the most about how players would perceive changes.

You have to put in real, effortful study on following games like the ones I listed above, though. Just being along for the ride doesn’t necessarily get you much. Also, experience working at a game company is almost a detriment here, because game companies I’ve worked at don’t spend any time looking at things like “exactly why did Virtua Fighter change this move’s recovery to 8 frames?” Instead, the focus is on actually implementing and shipping games.

I also think that you can’t really fake this. There is no way I could have accumulated the knowledge that I have if my motivation was to be better at my career. My motivation is that I am actually interested in things like this. Thomas Hoving was actually interested in art history. You have to live an authentic life in your chosen area of interest to develop true, deep knowledge of it.

Garcia vs. Sirlin (Analysis vs. Intuition)

In Street Fighter, there is no possible way to create a "balancing algorithm" that will tell you if Chun Li's walking speed should be faster. How good is faster walking speed compared to damage on her fierce punch, compared to priority of her ducking medium kick, etc? You could do a year of math on that and still be more wrong about it than my guess in two seconds.

I was very aware of this when I designed Kongai, and I tried to make it as difficult as possible to compare the relative value of moves because of their varied effects. I wanted valuation (the ability of players to intuitiely know the relative value of moves in specific situations) and yomi (the ability of players to know the mind of the opponent) to be the two main skills in the game. And then I encountered garcia1000, a Kongai player who came from the poker community. While my goal as a designer is to facilitate valuation and yomi, garcia's goal as a player is to play optimally without needing to make any judgment calls on those things at all. He want's to compute the odds and solve the game. You could say that he's my worst nightmare, but he is work is also fascinating.

This is the Kongai virtual card game I designed for kongregate.com.

Garcia started by creating several "endgame problems" in Kongai. He chose very specific situations, Character A vs. Character B, all other characters are dead, life totals a certain amount, fighting range set to far, item cards given, etc. He would give very specific situations (which were much simpler because there are fewer chioces during the endgame), and then invite other testers to work out the solution for optimal play. Each specific situation took dozens of pages of forum posts to settle. They would also show amusing things such as optimal play giving a 3% edge over the more obvious plays, in one case. It was also amusing that the math reequired to solve these endgame situations was far more complicated than the math I used to set all the tuning variables. (Because I mostly used intution....)

What you have to keep in perspective though, is how limited these endgame solutions are. You could know the solution to dozens of them and you wouldn't have solved even 0.00001% of the game. The number of possible game states is very large indeed, and each of these endgame problems that took dozens of pages of posts to figure out solved only ONE gamestate. If I had used rigorous math to solve Kongai during development, I could have been working on it for 100 years.

Trusting Intuition

If you have this iceberg of knowledge, or if you’re like Feynman who can rely on the icebergs of others, you should still know two things about maximizing the value of intuitions. Intuition by experts is better at solving complex problems than analysis, but:

1) The intuitive expert will be less sure of his answers, while incompetent people will be very sure of their (wrong) answers.
2) Having to explain yourself diminishes your ability to draw on your intuition in the first place.

This is too large of a topic to go into depth on here, so I’ll give only a short summary. There’s a wonderful study on incompetence that shows that people who are incompetent at a task (logic, humor, grammar, etc.) grossly overestimate their own ability at the task and are unable to detect expert performance in other people who actually are skilled at the task. The reason is that the very knowledge they lack to do the task is the same knowledge they need to evaluate themselves and others.

I don't know what this diagram means, but it seems important somehow.

The result is that you will definitely have to deal with the loud complaints of incompetent people who are quite sure of themselves, and who might even have a well-developed tip-of-the-iceberg of reasoning, but no underside to their iceberg at all. I suggest somehow gaining enough authority that your vague feeling on a balance issue is able to trump their loud complaints. You might even try explaining why that is best for the game.

Several studies show that explaining yourself wrecks your intuition. If you see a person’s face, then must identify that person later in a lineup, you will do much better if you do NOT have to explain the face in detail beforehand. Your explanation is imperfect because the bandwidth of words is so narrow, yet your knowledge of the face is nuanced. The story you create about the face overwrites your actual knowledge and makes you perform worse in the lineup test. Other studies show that requring an explanation of thought process makes test subjects less able to come up with creative solutions for problems.

While balancing Street Fighter, I had the luxury of not having to really explain myself to anyone, and that was a great advantage. Note that I happily explained everything after the fact, but I’m talking about in the heat of development. If I wanted to try a balance idea, and I wasn’t exactly sure why I wanted to try it, I could. I did not need to convene a meeting and lay out a logical plan that people voted on. I could just do it, and test it.

There was a brief period of disaster where a new producer tried to track every single task I planned to do in the balancing process. I was reluctant to submit any list of future changes because every day, the landscape changed. Tomorrow I might learn how to implement something that I thought before was impossible to implement. The next day I might learn that a recent change removed the need for some other future change, based on playtest results. Every day, the thing I worked on was whatever thing I felt was most important that day.

The agility that method allowed was amazing, and it's the only way I can imagine doing things. I think it’s pointless to track my work in the way that producer wanted to because doing so gives the overall project no advantage, while it damages my ability to draw on my intuition. Game balance has not been on the critical path of development on any game I’ve ever worked on, meaning there’s always some other thing that pushes out the ship date. In balancing, you keep doing it and doing it until someone says you have to ship.

By the way, I went back to doing whatever I wanted with no oversight fairly soon on the Street Fighter project, so mostly ignoring the new producer's requests was a successful strategy.

My advice to not explain yourself and to have the authority to ignore incompetent complainers unfortunately sounds like a recipe for creating an ego-centric dictatorship that ruins a project. Yet, the best way to leverage intuition is to gain that kind of power on a project, and then not use it much. You want your subordinates to do their best jobs without having to explain every little thing to you either, after all.

Conclusion

Balancing a game when we know we can’t know how to play that game optimally is a deeply troubling problem. Logical analysis often fails at this type of complex problem because it doesn’t take into account all the nuances that our unconscious minds and intuitions can. To solve this balance problem, or any similar problem, we should build up a vast mental iceberg of knowledge and experience in the field. I don’t mean fake experience like working at a game company or getting your name listed in credits though, I mean real experience which only comes from effortful study. Use your own iceberg of knowledge in the form of intuition and seek out others with vast icebergs of knowledge and rely on their advice. Finally, somehow acquire enough power on a project that you don’t let your valid feelings about what to do get trumped by loud disagreement from incompetents and don’t let your intuition be destroyed by anyone who demands constant explanations of your every decision.

Very interesting...

I also like the new site site design, and am very interested to hear what you have to say about flow (Positive Psychology, correct?)

For the lovely diagram you provided, the arrow represents a progression of skill in a given task. You begin incompetent and unaware of it, then you learn of your incompetence. Slowly you become consciously aware of how to do well, and at the end of it you make the correct decisions without having to think about it. You could be neat and call it Un-In, Co-In, Co-Com, and Un-Com if you wanted, but you probably don't.

In my chosen game I'm all over the place depending on the task, which is why I'm horrendously inconsistent with tournament placings. If you want consistent skill (and you're not intuitively badass at the game), you need to raise every area to a level of consciousness and work to improve them methodically. I've had to crawl my way up the tournament ladder through analytical experimentation over several years and I'm *still* nowhere near the level of intuitive professionals.

On the other hand, I can consciously explain more about the game and improvement as a result, which is why I'm a better teacher than many of those pros. Many of them tend to say stuff like, "I don't know, I just do it," which doesn't help raise the community skill level. On the other hand, they do a good job of setting the bar of performance for everybody else, and they win money, so who am I to criticize?

Also, I realize now that saying "it seems important somehow" is a joke, you understand the diagram, and that I'm silly.

Even though he can’t see so he has no idea whehter the stripes are horizontal or vertical, and sometimes become agitated when asked to guess, his “guesses” were correct between 90 and 95 percent of the time. In other words, people with blindsight can perceive the world more accurately than their conscious minds can explain.

OMG SUPERSTITION ABOARD!

Waterd: There's no superstition involved at all.

There is an explainably scientific way that this guy sees things - it's one of the two physical ways that things get seen in ordinary individuals. It's just that it's not the one that grants concious awareness, so he doesn't know what he sees.

I mean, I'm pretty sure that on the tests described, someone with normal vision would be able to identify the position closer to 100% of the time.

I wouldn't use that study as strong evidence for "competence means you have a better grasp of your own competence". It does indicate they cannot really distinguish well, but the strongest conclusion of that study is "people rank themselves as above average, but not massively above average, regardless of their actual skill level". Indeed, the most competent people consistently underrated themselves relative to their peers, and really the people in the third quartile almost always fell on the line from sheer happenstance - the third quartile and where people rank themselves simply fall in the same place.

I'm surprised you didn't bring up Chess as an example. In the game of chess, where both players have absolute knowledge, there is certainly a formula that could be followed to never lose a game. The vast complexity of possible situations as well as the large number of options available to each player means that nobody has solved this algorithm yet, but it is certainly there.

Fighting games, RTS, and other double-blind games are different though, as you have to use statistics as a mean to conquer the unknown. With super-human reactions, one could certainly make a formula to never lose in this context. A correctly programmed Virtua Fighter player could have habits that will ensure it never takes damage, only using the 'guard low', 'guard high', and 'low punch' options - only if it could evaluate the situation far faster than a human.

I enjoy the concept of solving a game, and it's certainly a difficult task, but it is also a reason I enjoy games with lack of information (especially fighting games) rather than games which are more apt to follow a formula. The first three moves in Chess have serious dedication to their impact and value - yet in the concept of a 'solved' version of Chess, only one is the truly optimal choice. The idea of operating on a sliding scale somewhere between 'bad' and 'optimal' is much less exciting for me than volleying the opponent for information and the competitive mechanics in a fighting game.

You know, when i was making my game, i used mostly intuition when designing the levels. I thought that meant i was making a bad game, or at least one that wasn't thought through, but now i understand that that sort of thinking is necessary most of the time.

I'm also a professional poker player, somewhat of an acquaintance of Garcia's. Serious poker players regularly break down hands in the same way a football coach breaks down video of plays. Examining the details of how we played a hand to try and look for weaknesses in our play and to consider better tactics.

I think your article has some misconceptions about what Garcia was really trying to accomplish by examining endgame scenarios and it really reminds me of poker n00bs who are overwhelmed by and don't understand the reasons for hand analysis. There are so many possible poker hands, what good is it to learn how to play any one poker hand? There are millions of possible hands and the chances you will ever play that hand again are minute. What's more, differences in your opponent's tendencies will mean that even if you do you will likely be playing the hand differently.

When you analyze a poker hand, you're not memorizing how to play that hand. What you are doing is developing your heuristics, your problem solving. You're not learning how to play THAT one hand, you're learning how to look for the KEYS to playing that hand. You are developing the skills to use the parts of that hand that will be similar in other hands. To bring it back to the essay, you are developing your mental iceberg.

I had nothing to do with Garcia et al running end game scenarios, but still I expect running those scenarios in Kongai is not all about memorizing how to finish the game (that would be chess). It's about isolating as many game variables as possible and exploring the game mechanics. Yes, there is considerable value in knowing that character A does better in endgame against character X than character B and so if you can choose which character to take to the endgame you take character A. But there are far further ramifications than that. If character A does well against character X in endgame, then that will generally mean that character A does well against character X in most situations. What's more, if we can begin to see WHY character A does well, we may be able to extrapolate to characters that share certain key similarities (ie; if character A is effective because of a particular attack, then other characters with a similar attack may also be effective).

Indeed, understanding how the cards interact with each other is vital to developing underlying strategy and tactics in any game. In science, isolating variables goes hand in hand with the scientific method. And in the case of combat games of any type, the way to analyze units is to first isolate and simplify battles to one on one. Then you can start to tackle synergistic issues as units support each other. In a game like Kongai, synergistic issues are far less important than in say Magic or Warhammer because of the way the game works with only one character in battle at any time and characters not currently in battle largely being unaffected by and not affecting the active battle. So isolating characters is a very effective tool for analysis. But it's not really about developing endgame strategy, it's about developing overall strategy.

Another thing worth noting about endgame scenarios is that you can direct endgames towards ones more favorable to yourself. This is actually pretty useful in chess; if you see a way to simplify the game to, say, a rook and king vs knight and king endgame, you might know that it is worth taking because you know you'll win that endgame. While its much more difficult in a game with hidden information, it isn't impossible, and I know that, for instance, understanding end-game scenarios in Magic is quite handy; I know, for instance, that if my opponent is at three life while playing deck X, my odds of winning are quite high, even if they wipe my entire board clean, because I'll draw what I need so and so often to eke out the last bit of damage. So if I see an opportunity to get them to a state which is likely to win me the game, I'll do it because I know that scenario and it favors me. So it allows you to see ahead and set goals for what you want to do.

"1) The intuitive expert will be less sure of his answers, while incompetent people will be very sure of their (wrong) answers.

The result is that you will definitely have to deal with the loud complaints of incompetent people who are quite sure of themselves, and who might even have a well-developed tip-of-the-iceberg of reasoning, but no underside to their iceberg at all."
---

I feel like this can be relied upon as a crutch by game designers (or any party trying to analyze feedback). It's basically a possible catch-all defense: 'sure they have laid all this reasoning out with high confidence, but my (or someone I'll deem an expert's) intuition is likely to be more useful.' There are many possible factors in why some players do less well in competitive play results (especially in team games with many moving parts), and losing games or displaying substantial confidence should not disqualify overall reasoning/analysis.

As far as the very interesting Dunning-Kruger study, sometimes the results can be misinterpreted. (My assumption here is that your passage I quoted above stems from the study, if not I'd be interested in where it does come from). While you're correct that the study showed incompetent individuals overestimating their abilities and the most competent individuals underestimating their performance, those erroneous estimations are relative to their actual results. This is probably in large part due to most everyone skewing their estimations of themselves and others toward "slightly above average" as Titanium Dragon pointed out.

However, on an absolute scale, more competent individuals still rated their own performance increasingly better than did less competent participants. So even if you only go by how people estimate their own performance, the highest estimates still belong to the most competent. (This is all expressed nicely under the segment in the pdf titled "The Burden of Competence"). This puts the lie to any theories that someone supremely confident in their reasoning/feedback is likely less competent than someone who plays games by "feel" or intuition alone.

One final point: this study was based on evaluating blind estimations of competence. Once made aware of how other people are thinking/answering/playing (such as seeing other forum posts or observing opponents' matches), the most competent players are actually much better at evaluating their superiority, because they've been stripped of the notion that everyone else is as good/competent as they are.

Sound a lot like a Titanium Dragon I used to know...
still, I don't know how much one could make a case for MtG given that the game is trying year after year to make its endgames less and less predictable and favoring plans with a variety of open path available more than plans with an (assumed) unevitable course.

"Also, I realize now that saying "it seems important somehow" is a joke, you understand the diagram, and that I'm silly."

lol he moved from quadrant I to quadrant II

Ha, I thought Titanium Dragon sounded familiar for some reason. :P

And yeah, I agree with Momo. In the last few sets, WotC has printed more and more expensive, slow cards that essentially read "You win the game". Cruel Ultimatum is the most obvious example, but the new Banefire fits that description as well, I think. I might even be worse. Basically, just about any red deck will want to maindeck a copy or two. The decks are already midrange, planning to win with a Demigod of Revenge. There's no reason, apart from space, not to include a random "I win" button that wins games you have no business winning. The freakin' thing even doubles as normal, if somewhat expensive, burn. It's just weird.

(And yes, Demigod itself is swingy as hell, but it just doesn't have the reach Banefire has)

FYI the diagram above where you wrote "I don't know what this diagram means, but it seems important somehow" is a representation for how one gains competence in a skill:

First, we are unconsciously incompetent (we are incompetent and don't even know it) "He is playing street fighter and doesn't even know the dragon punch exists."

Then we realize our incompetence (conscious incompetence) "He realizes he doesn't know how to do the dragon punch."

Then we work on it and work on it and while thinking through the steps we can consciously perform it (conscious competence). "Ok, I'm gonna dragon punch now. I have to press: Down, down forward, forward, punch"

Then it becomes routine and automatic (unconscious competence). "Dragon punch"
