My friend and I want to create a roguelike. We hacked stone soup a little, then ran out of time. I'm interested in EAs like ericb, and want to see, if combined with human creativity, they can produce interesting creatures. Also, once I have time, I've thought of implementing a MUD in scheme so that it is reprogrammable by the players. I'd use kawa so they also have the power of the java libraries.
