Other metaphors for the game of mafia

[Awoo]

Creature ran a really good newbie one:

Town is an illegal death cult suicide pact blood ritual conspiracy summoning an apocylypse
Mafia is FBI agents who are neutralizing them before they can all kill each other and summon the apocylpse

Lynches are blood sacrifice
Nightkills are FBI arrests

[Awoo]

It's a good metaphor and it really works out but its a bit intense to run it more than once in a blue moon

[Awoo]

More setups with good metaphors include safehouse mafia and Extradition mafia.
