From an epistemic point of view, the classical ingredients of a game (players, actions, outcomes, and preferences) are thus not enough to formulate recommendations or predictions about how the players should or will choose. One needs to specify the (interactive) decision problem the players are in, i.e., also the beliefs players have about each other’s possible actions (and beliefs). In a terminology that is becoming increasingly popular in epistemic game theory, games are played in specific contexts (Friedenberg &amp; Meier 2010, Other Internet Resources), in which the players have specific knowledge and/or beliefs about each other. The recommendations and/or predictions that are appropriate for one context may not transfer to another, even if the underlying situation may correspond to precisely the same strategic game.
