MUDs are an addiction!!
don't waste your time. I kind of wish I had started this last time on everwar. Good mud with many unique aspects to it.
the first mud i played was Rites of Passage, then Fate 1, then RoP 2 (briefly), Fate 2, and the last one was Methods of Destruction. Had high level characters on both Fate versions and MoD. Heck, I even have my own codebase running, but it is mainly to get some C practice. I may get it running somewhat publicly at some point.. Who knows.
as far as getting lost, the only mud i played fairly regularly that I never really memorized the map was MoD; the rest I memorized to the point i could outrun most automated scripts.
