Also, I've been experimenting with using this system for solo games. Ie. GMing myself.
This' worked really well but I only make rolls for my character, not for NPCs. So while NPCs may have aspects, these are only used for non-combat checks.
Thus in combat, NPCs have resolve which can be reduced, but the combat itself is dictated solely by the rolls of my character, whether those rolls be fail, success with consequence, or etcetera. This' made combat very fast and streamlined.
