The Munchkin RPG is a very evil series. The Munchkin card game featured madness, carnage, and a generally loose approach to both the rules and the spirit of roleplaying. In the Munchkin RPG, that bad attitude comes home to roost. These books feature abusive character classes, ridiculous feats, unfairly dangerous monsters, and more bad puns than you can shake a stick at. Even if it's the +7 Stick of Dragonslaying and Immunity to Rules.
