There was a very loose collection of RPG rules I had worked on back in the day as kind of a mental exercise. I just ran across it again today. Back then I called it Blazing Sonata, as the rules mutated out of an exercise in RPG system design I had done basing a rules light game on film noir and music. That linkage is gone, so the title Blazing Sonata didn’t quite fit. I’m calling it Edge of the Story as kind of a riff on Sword’s Edge.
Feel free to check them out and comment on them. I’ve never play tested these rules, though I would love to try. I believe it would need a group of players very comfortable with some level of narrative control, and with a willingness to further the story rather than just win.
