I just read through Fate Accelerated, a much condensed and simplified version of the Fate Core system. I think I now get enough of the basic concepts to step up to the plate with Fate. (Awww son, that shit rhymes.) I'm not going to do Accel as my game; it's just that the numerous examples and clearer writing have helped me get my head around how this works. Mostly.
I think I'm going to re-do how powers work, but I need to scribble some notes down before I decide anything concretely.
