 The main focus of this section is the local dynamics of what happens before, during and after a single game. There is also a broader perspective of time, in which all these activities are embedded in an extended temporal universe, large enough to include all possible trajectories of the game, finite or just as well infinite. In  evolutionary game theory,  in particular, infinite games typically arise from iterated play of finite games, with Lewis’ signaling games (2002) as prominent example in philosophy.
