I really enjoy playing this setup as a ranked game. I feel like it inverts the traditional mafia playing structure; typically, the town is responsible for acting as "hunters" and lynching mafia. In this setup, however, mafia assumes the responsibility of being the "hunter" by trying to decipher between who's president and who's fishing to be shot.
I understand that we still have the liberty to play it unranked, but of course people don't take unranked games as seriously and there's less of an incentive to play properly.
