Would you care to elaborate on where you found Jay (because BJ is such an undignified name) and Falcon to be particularly scummy? It looks like you put some time into evaluating MR, so I imagine you read the others as well. Thanks
The wincons aren't explicitly stated, so maybe there are wincons that involve things other than killing town or mafia in this game.
Perhaps a Serial Killer or a Survivor. That sort of thing.
