I'll just say this, vudu and GP got my MVP votes.
UncleBob is a close third.
Speaking of, something I'm going to add for my game will be, in the event of a townie win, holding a vote to let one dead townie share in the win. Say one of the townies was instrumental in the victory, but was offed by the mafia (ahem, GP), the vote would allow that player some of the glory, and even allow people in general during the game to play a little riskier. I think it might be an interesting addition to the game.
As for me, I lived through as a plain townie for the first time ever (I think), but only by acting like I could either BE mafia or by acting oblivious enough that I could be MANIPULATED by the mafia. I confided only in a select few via PM so they could avoid voting me out accidentally. Normally I like to be more involved, but was pretty busy this time. I figured this would be my best bet at survival, and it worked, well, thanks to our very active townie alliance!
Good game, everybody!
