Zero Player Game
A Zero Player Game, or ZPG for short, is a game where the player of the game does not actually control it, instead allowing the God of the Great Random to do all the hard slog of levelling up and fighting monsters. This is very suitable for a lazy player who would rather drink beer than kill 65 million boars. Nonetheless, games of this genre are rare, but fun to "play" due to the fact that the player can laugh at the hero's misfortunes without blaming himself for it. In these games, the human has little or no control over the game character. Godville is a fine example of a ZPG.
The main point of ZPG's is to provide fun, humor, or both to people who don't have much time to play normal lengthy games. Also, as with Godville, ZPG's may or may not be multiplayer.
