How about making a RPG based off the three books, The Obsidian Chronicles by Lawrence Watt-Evans. They're pretty simple books, and the world is well built. If anyone has ever read it, I
demand that they please PM me.
http://www.watt-evans.com/dragonweather.html has some info on the books, and since they're plenty combat filled, some people may like them. I'm a fan of optional text being what makes up RPGs, since lack of plot sometimes kills them for me. The land, for the most part, would repeat, but have different foes depending on skill level and progress. Eh?
