 Of course, logic does not presuppose that all players have perfect memory, or that they cannot pick up any information outside the progression of play. Epistemic action language can equally well be employed to analyze more general scenarios where the above axioms do not hold. Especially within dynamic-epistemic versions, epistemic logics can produce modified versions that cover many more cases than those described here (van Benthem 2014). Moreover, further modalities from epistemic logic make sense, in particular, those for common or distributed knowledge in groups of players (Fagin, Halpern et al. 1995; Meyer &amp; van der Hoek 1995).
