What I currently have for Mass Effect.
Visorslash, Takhisis, and KingMorgan count for their first roles (though, other than for Visorslash, the result would be Town/Lost/Didn't Survive Regardless).
Town: 22 (Askthepizzaguy, Autolycus, azzaman333, choxorn, CivGeneral, Daird, Double A, e350tb, edse, Jarrema, Kennigit, KingMorgan, MartinLuther, Mat93, mechaerik, Red Spy, SouthernKing, Sprig, Takhisis, TaliZorah, Visorslash, Yaropolk)
Mafia: 4 (BSmith1068, Frozen In Ice, spaceman98, Winston Hughes)
Won: 4 (BSmith1068, Frozen In Ice, spaceman98, Winston Hughes)
Lost: 22 (Askthepizzaguy, Autolycus, azzaman333, choxorn, CivGeneral, Daird, Double A, e350tb, edse, Jarrema, Kennigit, KingMorgan, MartinLuther, Mat93, mechaerik, Red Spy, SouthernKing, Sprig, Takhisis, TaliZorah, Visorslash, Yaropolk)
Survived: 6 (BSmith1068, Frozen In Ice, Jarrema, spaceman98, TaliZorah, Winston Hughes)
Replaced: 3 (MartinLuther, Mat93, SouthernKing)
I'm not sure if the final night mattered, though, or if the mafia were guaranteed a win after they went into the night with 4 mafia and 5 townies- but among the townies was a roleblocker and a role that could make itself invulnerable, so it looks like it might have still mattered, at least a little bit.
Zack, what can you tell me about this?
