If you like TGWBS, I can add a chaser rule where, instead of becoming a wolf upon slaying, the cursed villager becomes the anti-phantom of the village, having his/her entire existence based upon keeping him confused about everyone. Each night, the cursed villager PMs the mod with a cryptic comment, to be forwarded to the phantom. If the phantom accurately guesses the identity of the cursed villager, his side automatically wins. The downside is that once the cursed villager is revealed, the phantom dies. So if he's the only one left on his team, ironically, he'll lose.
Or... you know... not.

What a complicated addition to the game.
