I'm not sure why you are laughing, Agentt. There are mafia tournaments with money prizes, and it's not a one-off thing. And the way they play there is completely different from the way a bunch of friends would play.
Mmm, I know there are tournaments out there. World championships even, but it is the way friends would play that makes me laugh, the...fun part of doing stupid plays
Your description sounds more like Werewolf than Mafia but I get what you mean.
I prefer to watch people play it on YT rather than take part myself, since I'm socially dense.

It'd be quite difficult doing it manually. I used to play a discord bot called Wolfia or something and it could automatically host Mafia and Werewolf, but I don't know if the bot is still alive.
