In the rules for this game there is an example character that is part of the Triad. So I though I would put a little mob contribution to this game and list the skills I think are necessary for some mafia guys in this game.
Mobster (low-level): Streetwise, Drive, Intimidation, Brawl, Pistol, Subterfuge.
Button Man (hit man): Streetwise, Investigation, Drive, Pistol, Rifle, Brawl.
Boss: Streetwise, Intimidation, Interrogation, Savvy, Subterfuge, Pistol, Command.
Go sleep with the fishes!
