I'm wondering if Neutral Mafia - that is, everyone is third party - could work. The majority are survivors who can work together. The minority are serial killer variants trying to be the last one alive.
might end up with not many willing to lead town/non-killers though, since their goal is just to survive they may prefer to lay low and not paint targets on their backs. could be interesting if everyone's goal isn't that straightforward.
True, though they can't win with people who have to kill them. There would have to be maintained lynch vote pressure to contribute or die.
Considering trying DBZ mafia again, especially after reading through some Mass Effect and Jurassic Park mafias, which are/were pretty complex. Would start with a smaller game, the Saiyan saga for example, to sort of get my bearings as a mafia runner. Got some pretty good ideas though. Will keep posted.
Got numbers and roles sorted. Need a little help with planning the game though, as it's my first and has one or two unconventional things about it. If you weren't interested in playing and know a little bit about game balance, mind hitting my up with a PM? Ta.
