There is a game they run on forums over on BGG that looks like good fun.
It is based on the Paranoia RPG. (
Paranoia (role-playing game - Wikipedia, the free encyclopedia)) I think it would be great to run one here.
It is very different from Mafia. There is no voting. Everyone is armed with a laser and perhaps other devices/abilities and you can shoot each other almost every round. Here is a link to what is mostly rules about how they play it at BGG:

Would anyone be interested in trying it out here?
