I think Crackle could have taken the game much further had they known there was no mafia. It would still be a bitch of a road to climb, but they would have that much information at least.
A death miller or two may also have been necessary among the otherwise VT's.
I don't know. Xv1 just seems incredibly hard to balance. But I love the "Game of Cops" concept! I'll give it a 6, because conversation was really starting to get into it on D2, but we just got lucky
