Megaspace / Megaspace
The Megaspace was an early space opera setting I made up, but never got around to using much. All that came out of it was a crappy text adventure, a couple of short stories and a play-by-post roleplaying game. Oh, and an essay titled A discussion of science fiction cliches, which is now pretty much obsolete. But it was a lot of fun creating it, and I learned what not to do. Maybe one day I'll write about that.
