When you just want to beat up on your friends without actually hurting them, ROLF! is the game to turn to. With quick character generation and a fast-moving combat system, it's a silly little game that puts the die-rolling in roll-playing games. With this game, you really get what you pay for!
Designed by Steve Miller (formerly of West End Games, TSR and a few other bankrupt RPG publishers) and L.L. Hundal (formerly of nowhere, because she's much too smart to enter game design on a professional level), this is the perfect game to pass the time while waiting for late-comers to arrive for the RPG session... or while you've been kicked out of the room, because the GM and another player or two are engaged in some secretive, story-based roleplaying nonsense.
