Triadcity is an original, totally free MUD in which players have more to do than find and smash monsters - Roleplaying, non-violent interaction (such as journalism, Cartography, and more) and of course, vicious combat are all here in abundance.

This MUD is intended as a form of literature, not merely a game. As such, the entire world is very 'smart', with hundreds of literary references and many fascinating locations. Unlike most MUDs, this one is set almost entirely in an urban environment, and is not limited to medieval-era technology(although medieval weapons and the like are very common).

If you like to think and you like to read, then give Triadcity a try. It may be just the change of pace you've been looking for. Still in Beta, but progressing steadily, so get in on the ground floor. I've enjoyed my experience so far and still play to this day!
