I remember seeing an actual play of “Fall of Magic” posted by Ross Cowman and being struck by how very, very different the style of roleplaying in that session was from what I typically do/see. It was very verbally instead of visually oriented, lots of description of internal thoughts, each player almost languidly describing their actions as well as the scenery around them. After reading your post, Paul Beakley, I think the difference can be explained by my play having a much more filmic quality, while theirs was much more like prose or even poetic written fiction. They were much more literally indulging in “collaborative storytelling” then is common in my circles.
I think “Fall of Magic” was very informed as a design by that style of play, it forces that style upon you to some extent.
