Reminds me a bit of my “Kill 'Em All False Flip” Mafia game I ran on this board a bunch of years ago. It was called “Inblorious Gasterds”. (Which is a reference to both the Tarantino movie and the Batman Mafia game that was run on Idle Thought’s Mafia board–which was also the first Mafia game I ever played in.)
It was bastard mafia, but with a specific set of rules. There was nothing arbitrary and the game could have been won by everybody. Or only one person. It all depended on how the players played it when it came down to the last three players. There was no town. There was no scum. Everyone was a serial killer…but instead of actually submitting a target to kill at night, they submitted a name that would be collected with all the other names and it would act as a secret vote where the top target or two would be killed each night. During the day, the top vote getter would be killed by the players. If more than one person had the same number of votes at top, each would be killed. Each player had a preassigned reveal which matched stereotypical town/scum roles. Before announcing each death, I PM’ed the dead players letting them know what’s up because obviously the flip was going to surprise them. If the final three players (which since I controlled how many were killed in a cycle, I guaranteed that the final Day would have three players) all circle voted, they would all die, and everyone would win. If anyone got two votes, the player who didn’t get voted on that final day would solo win.
Of course, the players didn’t know any of this, other than they were playing a bastard game. But I played everything straight, even up to the point where the first 6 deaths were all players with Vanilla Town as their flip. (People wondered if it was an all vanilla game at that point.) I even had some spoiled observers wonder why I didn’t fudge the flips, and I said the only cheating that I was doing as mod was that I was lying about the death reveals. Everything else was completely on the up-and-up.
Some spoiled observer that had died the final night accidentally let slip at the final day the whole thing by posting to the game thread instead of the spoiler boards, which it must be said were on an entire different server from the SDMB. I reached out to the mod to delete it, and it was deleted eventually, but it was seen by the last three players. They literally could have gamed the entire thing to have everyone win, but one guy got too clever and didn’t believe what he saw in the spoiled post and figured he could vote one of the other players who already had a vote on them, while he himself had a vote on him.
So the person who didn’t have a vote on them got a solitary win when Day ended.
And as far as the partial scum/partial town, thing. There’s always this:
