I just read all the chapters on Narrative gameplay and WOW, this is so great. I've been scratching my head on how to make the mecanics of PTBA moves (but not fully PBTA) work with a Stress system, a narrative magic system that doesn't limit players, but still scaling, lignages, backgrounds and classes for characters and hitpointless enemies for months, and you just made the best version I couldn't even think off. I'm eager to test this system with my players, thank you so much.
I also love how the bast rules for narrative gameplay are still pretty generic, making it compatible with other setting.
Great job, and I really want to see how this'll turn out.
