I heard about this from the episode on Yes, Indie'd. I have to say, I have been looking for a good PbtA/Story Game framework for telling stories across many different realities for a long time. There have been efforts that have come close, but this, oh this. :)
I'm curious about the floral cover designs for BtS, though. Does anyone know what the inspiration is for them?
It makes me think of the Voynich Manuscript.
