you basically hang out in a chat room and then after about five minutes, everyone is kicked out except the people who are "mafia". these ppl get to chat about who to kill and then once they're done in the morning, someone dies and the town tries to find who the mafia are
but then there's the vigilante.
he works on his own, trying to guess who the mafia is and killing one person a night as he sees fit
but what usually happens is the vigilante gets drunk on power. he can kill whoever he wants at night with no consequences!!!
and usually he ends up being this huge nuisance to the game, guessing the wrong mafias and killing innocent town folk. and then he always goes out in a blaze, either being lynched by the mafia after they guessed who he was or the town for thinking he was bad
so sttylllee since there cant be substance when you're going off whatever you believe in your own head
