I finished a playthrough of this today - I played solo using the 'brief correspondence' variant, but there was nothing brief about my time with the game - I filled 50 sides of A5 with my world building and journaling! Basically, I loved it. My story flowed very naturally from the prompts, which were varied and provided twists and turns for my characters and the 3 stage process became second nature very quickly. It's just a fantastic game!
