I have an idea about how we could do an interesting mafia/nomic combination for winning.  Since the mayor is dead, it makes sense that the people of the town would elect a new one.  Thus, let us have a rule concerning the “election” which presents the possibility that we can somehow have people “in the running” for mayor, and they pull in votes.  Cunning werewolves can pick off opposing candidates and the town can lynch those which they think are werewolves trying to take over the city.  Set some kind of goal which is trackable (perhaps having a certain percentage of the village supporting your efforts for a certain period of time?) that we can use to measure how close someone is to winning?
