Similar to the assassination there's Mafia, I used to play it and it's funny too.
I could host the first one.
I just want more bloodbath and have everyone working on my commands like little pawns.
There's also Werewolves, based on a cardgame. I think it's similar to Mafia (but not sure). But it's great fun as well
I'd love a music talent contest. I don't know if there's enough musicians here though.
I honestly think it's a good idea. I know an Idols-style competition was suggested here earlier as a joke (and I also responded to that) but I do think an actual talent competition would be great. But it would probably have to be something like an annual or semi-annual thing to maintain interest.
