I just finished reading The Predictioneer's Game
by Bruce Bueno de Mesquita and it has really started to make me wonder what situations could game theory be applied to in every day life that we aren't applying it to currently.
In his book he goes into detail about how he has setup a program where he identifies the players in a situation and defines those players based on a number of parameters that affect how they interact. He uses this to run game theory simulations with rounds that move the players' stances each round until some form of equilibrium has reached that gives an answer to the controlling question. He's used this for everything from determining the outcome of a political race to his most recent publicized issue of whether North Korea will build a nuclear weapon (which I believe he may have done a TED talk on).
Anyways, if you can make it through the first 15 or so pages of him patting himself on the back for his accomplishments I think it is worth a quick read.
