The Munchkin franchise by Steve Jackson Games is one of the most venerable in gaming today. It doesn't have the lengthy history of D&D or even Magic: the Gathering, but it wouldn't exist without them. The whole point of the game is that you are a munchkin... That is, you are a role-player who doesn't view RPGs as fun games and an exercise in improvisational acting, but rather as fun games where you kill monsters and take their stuff by maximizing your stats and dice rolls. There are quite a few versions of the game. The most well-known version is the original fantasy version, but there are versions for science fiction, kung-fu movies, the Cthulhu mythos, the Axe Cop webcomic, and more. However in all of those sets you play as the "heroes" killing monsters. Munchkin Zombies is a more recent set where instead of playing as a human survivor in the zombie apocalypse, you play as the zombies, hunting down humans so you can eat their brains.
