IdleRPG

IdleRPG is a game which involves no player interaction. Players simply sign up, and the game takes care of the rest, from battles to quests. The Fybertech chat server runs a modified version of the game, however, with many of the penalties removed, since by default, players are penalized for talking. Since the game takes place in the main chat, this seemed to be a necessary modification.

Suggested by Buzzard, the game has actually helped boost participation in the chat.
