Kingdom of Loathing

And the winner of most irreverent game goes to... Kingdom of Loathing, a turn-based RPG that is just... well you'll have to play it. Players take on the role of six character classes, including the musclebound Seal Clubber, the Disco Bandit or the rogueish Accordion Thief. Creatures you need to overcome include Sabre-Toothed Limes (ouch) and Ninja Snowmen. And the items... well lets not get started, but they're definitely not your regular D&D Short sword +1 material. There's also cool merchandise, to let folks know how coolly subversive you are. PS: Don't drink too much Mad Train Wine.
