I was bored today and thought up something interesting that I might try after I run my Legend of Zelda mafia game. Recently I've started playing D&D for the first time and I was thinking of a way to incorporate those mechanics into a mafia game. Here is what I came up with:
The 'scum' group will be an adventuring party that is on a quest. The 'town' would be all of the monsters in the game that are trying to kill the group. Each monster would have a certain HP and the party members would each have attacks that could lower the monsters' HP at night.
For example, say there is a goblin and I give him 5 hp. The party members would use their abilities at night and lets say that the Ranger hits the goblin for 3 hp and the fighter hits him for 2. The goblin would then die. The monsters would not know when they were hit (unless they had an ability) or how much HP they had left. So the party members could choose to all concentrate on one person each night and kill that one person, or they could target different monsters and lower all of their hp without the monsters knowing. Each party member would have a smattering of different one shot abilities that they could use in place of their standard attack (like in d&d) and most of the monsters would be empowered as well.
There would be a variety of other little things to add flavor, but that is the gist of the gameplay. The story would follow the adventurers on their quest to slay their arch enemy (a very powerful townie who dooms the town if he dies). The day phase, instead of voting, would have people attacking each other. Once one player is attacked enough, he is killed by the monsters. It's still basically a bunch of ideas right now, but I'm not sure if it would have enough support to run.
