As for the type of game, I have no problem with a themed game, as long as its with Vanilla role setup. Cop, Doctor, Vigilante, Serial Killer, Mafia, and Town. Thats it. Even a Hitman for the mafia and Masons for the town is fine as well. But no need for a Mafia Doctor that is also a busdriver and can cure the SK to turn mafia, or whatever other combonation you can think of.
Oh, and absolutely no Cults.
