This essay describes two different phenomena: action games, understood as a genre of games in which the player’s sensori-motor skills prevail over his cognitive activity, and a general theory of action-taking in context of the game-playing practice. Through a short history of the main genres and sub-genres traditionally identified with “Action games”, and the conclusion that such a categorization pertains to a mode of action rather than a given genre, the properties of action games are identified as involving a standardized repertoire of actions, emphasis on sensori-motor skills, and short-term action sequences.
