I get why game theory is an attractive model to explain human behavior. But I always wonder why they invent the game, and try to explain behavior in terms of a particular model, rather than using real behavior to fit model parameters, so you could get (pseudo-) empirical numbers for "payoffs" etc.
Or maybe another way of putting it is that clearly rational and human behavior varies with the payoff structure, so it would make sense to include that as another variable.
