Oh i'm a good Mafia man. I have the Mafia name and everything. (Classmates gave it to me when i made friends with a policeman in Rome) Tony Tuvillo.
The game itself is interesting, but you need at least 15 active people to do it.
I, however, have a dungeon-crawler game on paper somewhere that i could easily adjust to be more manageable, and it's playable with 4 players up. (It's more of a roleplayer than a real game, though)
