I am a new member to these forums, but I signed up to ask for guidance and possible inspiration. I spent my youth playing role playing games, but the group scattered around the country, and I picked up war games and miniatures later in my gaming career. I am familiar with the original Feng Shui rules and have played them, so I thought this engine would be ideal to run the kind of game I'm contemplating.
Some might consider it blasphemy, but I want to use miniatures with a free-form system to emulate the action from the movie Boondock Saints. Feng Shui seems ideal for that. Few stats, guns and action plus the emphasis on attitude and badassery. The brothers MacManus certainly fit into the action movie template.
I don't have the FS2 book so I'm basing this on my knowledge of the first edition rules. There are some issues to cover. Firstly, the "static" nature of miniatures battles on the table versus the high-flying action of imagined role playing combat. I need to assign movement values to figures, something like Speed = movement in centimeters. Stunts would simply expand on this and provide extra movement whenever a good narrative (no reason to ditch descriptive combat just because there are miniatures on the table) is provided. Simple enough. Range bands for shooting? I don't remember that from the original rules. Ammunition count and reloading is there, AFAIK. Scenery is tricky but doable with a little imagination. The "battles" in this war game/RPG adaptation would be based on the fights and shootouts of the original movie, plus extended content when the campaign has been going on for a while, down time decisions before and after scenarios (opportunities to use skills and shticks outside combat), and an expansion on the lore of the movie (haven't seen the sequel yet).
There might be a point I want to expand the game into the realm of regular Feng Shui lore in a limited sense, or just choose other movies to base the game sessions and characters on. The other possibility is to take other RPGs and steal a setting or characters from them, just to provide some variation to the campaign. The game will probably be a mix of different cliches with the undercurrent of religious vigilante violence.
