MUSHes and MUXes - the essential difference
Hey.
Long-time MUSH and MUX player (and staff member) here. Honestly, I find MUDs to be pretty dull, for the most part. If you're looking for a video-game atmosphere with a little RP in it, like most MMOs, well, that's probably your forte. MUSHes and MUXes, however, are almost universally RP-based, with a much smaller degree of hard-coded die rolling. Many of these have some of the most astounding RP I've ever encountered, although it's easy to get hooked, much like MMOs but many people also develop a severe emotional investment in their characters as well. Still, the strength and variety of RP you can encounter in these places is often-times worth the valuable hours of your life you waste on them. I'd highly suggest giving them a shot (and there's a number of them that are D&D/D20 based, too) as a player before trying to run one. That way you'll be able to determine:
A. If this is your style of gaming in the first place, and
B. You'll be able to recognize the all-too common pitfalls of many staff, judges, wizes, etc. and
C. Recognize a niche that you'll be able to fill, since these places are often cut-throat and competitive since the player-base has slowly started to dwindle in many MU*s over the last few years.
If you'll got any further questions, I'll be happy to help how I can.
