Everything is an inspiration for my games—but I can’t think of any one thing that’s particularly noteworthy or recurrent. Mostly TV shows and books—the usual suspects. I suppose the one thing that might be a bit odd is that I usually am more inspired by other genres. That is, when I’m running a supers game, I tend to look to every genre except supers for inspiration. When I’m running a space opera game, I’m likely to lift ideas from detective shows or fantasy novels. And so on.
I’m a huge fan of genre mash-ups, crossovers, and genre deconstructions, so I generally try to create something similar when I’m creating a game, running a game, or even, to the degree that I have the input, playing in a game. Looking to a genre other than the one I’m currently running (when I’m running a single-genre game) thus gives me inspiration.
