Okay… Firefly-Serenity seems a good fit for a MG Hack:
Premise: do the job. Get paid. Keep flying.
Missions: smuggling, robbing, protecting, defending… lots and lots.
Conflicts: there are enemies (the Feds and corporations, plus all sorts of mean people on the outer planets and moons, and one nasty gangster).
Weapons: fists, improvised stuff like pool sticks, and, well, guns:)
Overarching Conflict: survival out in the black.
Territories: specified inner and outer planets and moons. In local terms, ships?
Denizens: hoo, yeah: Reavers, humans toting shotguns… incredibly powerful corporations…
Skills: pilot of course, gun-oriented skills, some stuff that is western oriented such as riding, perhaps disguise…
Abilities: obstacles–think of stuff from the shows; what would you do here?
Traits: hmmm, Browncoat is obvious… how about Courtesan? And of course, Psychic…
Recruitment: anyone care to take a stab… let’s see if we can flesh out a hack that works well and captures the feeling of the 'verse??
