I've converted the caves of chaos into a rules light system I've built personally. The system plays out somewhere between FATE and D&D, with emphasis on player creativity but enough rules to keep things from getting completely out of hand. I'm looking for 3-4 players, and I'll, of course, be more than happy to run you through the system; its quick to pick up. Expect 3 hours of solid crunchy combat goodness and some fun along the way. PM me or post here if you're interested.
