Okay, that makes sense. If I remember correctly from #lisp and #lispgames, it seems like you spent quite a bit of time on getting the map generation to work. My own game finished in a kind of bad state from a similar problem. I spent a lot of time on getting networked multiplayer to work only to realize that almost no one would use it.
Yes, it certainly is better than nothing, and it does looks pretty good. I'll take a look at the code you mentioned. It sounds pretty interesting.
