This book is frankly brilliant, and I haven't seen a group jump to play something from just the pitch as quickly as they have for this. If I have one criticism, it's that the book takes a lot of time telling you what the fluff is, or what the subtext for a playbook is. RPG's are about finding what resonates with you in what's there, but I doubt Erika is going to break down my door when I use the Witch playbook for a Zen Monk or what have you.
