You know, I really envisioned this to be a bloody game. I mean, potentially four people could get killed any one night (vote, mafia hit, vader hit, killer hit), even letting actions overlap and all (so all night actions happen, regardless of order), and it just didn't happen.
The mafia hit being blocked when the godfather is voted out is something I didn't include in my first game I hosted, but I came to understand its strategy afterwards... It's a way for the townies to stop a hit – a reward for a good vote. Kind of a check and balance. Its effect is magnified in a game like this, though, where the mafia seem to be hanging on by a thread.
