Everything is imperfect. Sounds interesting. The only similar game I have played is Microscope which is world building a scene at a time. I enjoyed that a lot. I also find the dice pool interesting. You get curves and you get to roll a lot of dice at once which is always fun.

The dice pool mechanism in *Engine* (not *Bones*) with its aspects and rolling ones thing is actually very nice. It's quick. It's easy to explain and understand. The "auto ones" thing for skills is a clever way of having skills make you more reliable at certain jobs instead of playing the escalation of difficulties and penalties game.
