Here's something I've toyed around with before in private chatrooms, with fairly good feedback. If there's interest, I might run it in the Micro queue once I'm allowed. Let me know what you think:
Don't Be Yourself Mafia
5 VTs
1 BP SK
2 Goons
Several games (rounds)
are played by a group of 8 players, with the same setup and
the same role distribution
. Before each 'round'
anonymous alts are randomly distributed
among players for use in this game, such that players are newly anonymous at the start of each round, but know that everyone has kept the same role. The actual playerlist is hidden until the end (and nameclaims can be disallowed). From round 2 onwards, it is equally useful to identify people by their posts, as it is to scumhunt.
The actual setup can be anything from 3p LyLo to a standard 9p Micro, and the winner is determined by 'first-to-two' or 'first-to-three' rounds won. Replacements are a no-go, so this would need committed people, and probably something like WotC.
