I'm currently a GM over in the PEBA and one of the things I've done over there is to host a few games of Mafia. Mafia is a party game that pits a small number of Mafioso who know each other against a larger number of townies who don't know who anyone is. The object of the game is to kill off the other team by voting each other out.
I'd like to get several more players if possible. The games are quite a bit more fun with more people. You don't have to have any interest in joining the PEBA to play, but you would need to sign up on the PEBA forums to do so. You can tell them I sent you for that purpose when you register.
Oh, did I mention that the game narrative will be illustrated in Lego? Check out the sign up thread and you can find some examples of the first 3 games I hosted over there and more information about what Mafia is. Playing online is a bit more intricate than real life Mafia, so check I encourage you to check it out even if your remotely curious. It's a ton of fun.
