Which one? The Killing Game?

Bingo

Well, it's a game where every night, a person is killed, and during the day, an investigation is held to find out who is the killer. Voting will be used to determine who it is. The person with the most votes is executed, and his role is revealed. The last man standing survives. Hope that makes sense.

So, Mafia.

Somewhat. There used to be a lot of Mafia games on the forum, even warranting their own thread, but they retired in 2018, and were essentially replaced with the annual Killing Games. From what I understand, the traditional forum Mafias were more fast-paced than today's Killing Games, and would say that the Killing Games are more structured.
