Cow Goon
(i.e. a "normal" anti-town faction that isn't Mafia or Werewolf, but rather a third anti-town faction; if any "unspecified alignment" roles are rolled along with this, at least one becomes a Cow, otherwise this is effectively an SK)
This one is a complete mess :-) It has four effective VTs, a Werewolf (with an ability that allows them to automatically lose, which they should use because win conditions are reversed), a Mafia (with an ability that they should probably never use, as with reversed win conditions it'll make them lose and everyone else win), a player who gets to choose their own alignment, a role from the Worst Roles thread (which is statistically probably an almost unwinnable third party; I randomly rolled
398 which fits that description quite well) and a player with no specified win condition;
and
all win conitions are reversed. I'm not sure if the reversal of win conditions is public or not; if it is, the game is actually reasonably balanced (although the Werewolf automatically wins and plays Kingmaker to some extent), because the fragmentation of anti-town factions works quite well with the Vote For Town mechanic. On the other hand, unless the choose-your-own-alignment player happens to pick Mafia, it's either Not Mafia or becomes so very quickly when the Werewolves kill each other overnight.
If the reversal of win conditions
isn't
public, it's about as bastard a setup as is possible to create.
