Love this--I use it in my Introduction to Game Storytelling course to teach environmental storytelling. The rules restricting discussion of lore interpretation and the wanderers interior states are brilliant. Love the rotating roles of world and chorus too.
I finally got around to reading this after backing it on Kickstarter forever ago. I think the scenarios and inspirations are truly wonderful, and are a great resource for anyone who'd want to evoke a bleak and mysterious world.
