By variations, I mean like it's own kind of Mini Mafia. You know, PokeMafia I or Dethy Mafia II (you guys know what dethy is, right?)?
I would say it's best to just keep games under the main series or mini series, and the variations can go under one of them. (like Kingmaker will for mini mafia) That ensures we don't have anymore than 2 games going on at once. Or 1, depending on what hosts decide, as Oath is waiting for Mafia 5 to end first.
