I've played this and recommend it.

I've also found another recently created game [1], Secret Hitler, which seems to be heavily based on Mafia, except in this case the informed minority / bad guys are Hitler and the Nazi party. It looks really good. Designer Max Temkin (whose Kickstarter account owns the linked page) apparently worked on Cards Against Humanity. I haven't personally tried Secret Hitler.
