A description from Greg Costikyan:
Aki Jarvinen has posted cards and rules for GameGame 1.0… which he pitches as an attempt to do for games what Understanding Comics does for comics: that is, to provide insight into the nature of games in a game, in the same what that Understanding is both “about comics” and a comic.
Thus, his cards are things like “Goal” and “Environment” and “Victory/End Condition.” There’s both a coherent set of rules for determining victory and a roleplaying element: players must improvise what the game they are creating is like, e.g., describing what their “Victory/End Condition” is–but they can only have one if they have the relevant card.
Version 2.0 recently became available at the website below.
