Re: General OOC
Black Sabbath is the original inspiration, of course, but the game as a whole spreads widely through NWOBHM and power metal (no way to make NWOBHM a game stat though). And there are references in the rulebook to others as well.
As I've had a couple days to mull it over though, I'm back on the fence - on one hand I like the tone, on the other hand it feels like maybe the wrong kind of meta, pulling players out of the game rather than immersing them deeper into it. I think I'll need to get a live group together, at least for a one-shot, and see how it feels when I tell someone to roll Prog.
