It's my first time even touching on designing a setup, be gentle.
Setup:
1 Mafia Framer
1 Mafia Godfather
2 Sane Cops
2 Insane Cops
1 Paranoid Cop
1 Naive Cop
1 Results Cop (gets "Innocent" if target is the Godfather or a townie who got correct results, "Guilty" if target is the Framer or a townie who got incorrect results)
Every player who is a Cop is not told which version they are, and will be revealed as "Cop".
Scum will flip as "scum" but not reveal which role they had.
I didn't get very far into thinking out breaking strategies, or if the results could even be used. But I wanted to throw it out there.
