Discworld Mud
discworld.starturtle.net
Discworld MUD is a multiplayer, text-based online game based on the Discworld books as written by Terry Pratchett. On Discworld you will meet many of the characters from those books. Terry's books are humorous fantasy and the game retains the comical, fun feel of the books.

Thought I’d post this up here since I’ve not seen it mentioned. For those who want to explore the world of discworld, this is a great MUD.

Very friendly community when I hop on every few months, and with a lot of rich detail from the books.
