I'd say the MUD suffers from a serious lack of new content. If the MUD stopped updating long enough, or updated irregularly enough, or was just uncomplicated enough that you could easily learn everything about it, then yeah, I'd start to lose interest. Still, I think the number one thing that keeps players on any MUD, rather than the game itself, is the community. Have a good one, and you'll at least keep a dedicated handful of players, even on the most horribly un-entertaining of games. Still, there's gotta' be at least something to the game there, or we'd all be hanging around in IRC, not on MUDs.

Just my two bits.
