Gore Fest: Words Not Deeds

From the introduction:

Playing Gore Fest requires no math. Its players do not have to memorize complex rules, and may enter the game in a matter of minutes. Gore Fest is an adventure game of the "role-play" type, where one player takes on the special role of "game master," a kind of referee and story-teller, and the rest of the group assume the "roles" of characters, the protagonists and antagonists of the night's story. The latter group, referred to simply as "players," after the theatrical term, are responsible for directing the actions of their character alone. The success and failure of this character's endeavors are determined by the game master with reference the rules and an element of random chance.
