I'm messing around with a simple little idea over the weekend. I was talking to Brian a little while ago about maybe trying out Dungeons & Dragons 4e, and I've recently been thinking about how Mutants & Masterminds could be used to run a fantasy game, so I've generally had fantasy campaign settings on the brain.
So, just for the hell of it, I've been writing various fragmentary campaign setting/plot elements on bits of paper, scattering them randomly on the table, and then arranging bits that seem to work together into rough relationship maps. It works beautifully. I definitely want more setting elements to play with, though. Maybe ones written by other people. The concepts I put together are familiar to me, since they're made up of components that have been rolling around in my head for a while, now. I've gotta try this game with other people, some time. That sounds like a hell of a lot of fun.
