  • Best MUD engine I have tried, very modern.

  • This is THE best codebase for newbies and pros alike! The ability to modify your mud inside of your browser is an excellent feature and the creator responds quickly to any questions you post in the yahoo group. Try it!

  • An excellent MUD codebase; has all the features you can want (and then some), absurdly easy to administer, and since it's Java it'll run on near anything.
