““Videogames require critical interpretation to mediate our experience of the simulation, to ground it in a set of coherent and expressive values, responses, or understandings that constitute effects of the work. In this process, the unit operations of a simulation embody themselves in a player's understanding. This is the place where rules can be grasped, where instantiated code enters the material world via human players' faculty of reason. In my mind, it is the most important moment in the study of a videogame.””
