problems with some of yalls suggestions...
1. crewmate mode
this is the most suggested one. the problem with this is pretty apparent. say your a crewmate, and you die. what now, its gonna be boring as hell.
2. two imposters
the problem with having two imposters is that it would be too easy, and... the ai would sometimes do things you don't want them to do. PLUS if crewmate mode is ever a thing then this would conflict even more.
3. more sabotages
sabotages like o2 would have the exact same reaction as reactor, its just two different spots. comms would be interesting I must admit, maybe getting to vent without getting meeting... oh wait that's what all the other sabotages do anyway. comms would be useless.
4. online
this should be pretty obvious.
5. voting
the only way i could see this working out is in crewmate mode. i would expect it to work like this: as a crewmate whoever you vote, all the bots vote that person. as imposter it would just be a waste of time, and kind of lame.
