Broadly speaking, much of the epistemic game theory literature is focused on two types of projects. The goal of the first project is to map out the relationship between different mathematical representations of what the players know and believe about each other in a game situation. Research along these lines not only raises interesting technical questions about how to compare and contrast different mathematical models of the players’ epistemic states, but it also highlights the benefits and limits of an epistemic analysis of games. The second project addresses the nature of rational choice in game situations. The importance of this project is nicely explained by Wolfgang Spohn:
