Over the last six months I have been porting the 1981 version of Rogue to CL. My intention was to learn the basics of CL; it's a straight port of the game. I wish I had thought of porting something sooner (especially Rogue, which I once ported to PC/GEOS), but for some reason this didn't occur to me until recently. It is a great way to learn a language if you don't have much time.
