 So what is game theory? Game theory is actually a very recent mathematical field that is used in a bunch of other areas. It's used in war, it's used in biology, it's used in politics, and really all game theory is the idea that you can study and describe and maybe even predict the behavior of rational actors making decisions and maybe cooperating, maybe competing. It's actually a fairly open field. I mean almost everything you do is some sort of cooperation or competition and you're making some sort of decisions. You believe in free will at least. Now game theory in terms of games is a little tricky because the math is usually not useful. Like really not useful. You'll study all the math of the prisoner's dilemma. It's not going to help you win games.
