How about a game where the town are all pizza delivery boys desperately trying to get off deliveries on to the management training program? The "mafia" would actually be evil customers with devilish schemes to refuse to pay and blatantnontippingitis, who depress the poor delivery boys they target into giving up the management dream. There could be some neutral management types who's role I can't quite decide, and items such as cars, bikes and fake exploding pizzas to help the delivery boys reach their dream.
