Hey, thanks for the quick reply! You said, "The powers are the things each character can do," but what are the things characters can do? You mentioned Star Wars, Firefly, and Dune as some of your inspirations; the things considered to be "powers" in those settings are quite different from one another! Since it seems like your game implies a setting, I'd love to know what kind of things you picture PCs capable of doing in that setting!
I do really like the supply/pool dynamic and the failing forward, and will probably use something like it in a game I'm running!
