I'm trying to stick to the idea that day & night talk can be really fun, and therefore trying to think of the setup where that can be possible, like already suggested Matrix Movie mafia.
The idea is that only teams can day & night talk between each other.
There could be 3rd parties also and mixed teams ie. town+mafia.
Only team win would count (the last surviving member wins for the whole team).
Mafia could kill mafia.
Mafia from one team can't talk with mafia from another team.
First idea: Mafia Dubs Shootout
Don Vito Corleone & Michael Corleone
vs.
Carmine Falcone & Al Capone
vs.
Tony Soprano & Nino Brown
vs.
Tommy DeVito & Santino 'Sonny' Corleone
vs.
Vincent Mancini & Paulie 'Walnuts' Gualtieri
All are mafia, but you can talk only with your teammate anytime.
All teams have one NK per night, and regular lynch per day.
If two gangs target the same mafioso on NK, Shootout happens, but no one dies.
There could be additional roles like mafia doctor, godfather, ninja etc.
What you think about the concept, could this work since Matrix probably wouldn't?
