I saw some of the discussion surrounding the new Story Cube game's release, but I'm not sure it's a good buy for my solo gaming needs. I do own 3 sets of Story Cubes, and I've used them in the past to do a kind of freeform world building with my RPG group. Does anyone know of a more structured way to use the Story Cubes for solo gaming, or is it best as a purely freeform oracle?
