While that is still a great way to play M.U.L.E., we think there is a better option. OpenMULE is designed to "resurrect" this great game, with a modern code base that runs on modern machines. The goal is to maintain the gameplay and feel of the original, while providing modern graphics, sound, and Internet capabilities. Additional features may also be added, where these do not detract from the spirit that makes M.U.L.E. such a lasting classic.
OpenMULE is a complete rewrite, sharing none of the code or other assets (including graphics and sounds) with the original. It will always be free, with source code available, and should run on any modern Windows, Mac OS, or Linux machine.
You can also directly contact the primary developer, Joe Strout, at firstname.lastname@example.org.
In addition, we now have two very talented artists working on the project: Jeff Quan, who previously worked with me on such games as Armageddon and Zombies; and Mike Mann, who had already produced some M.U.L.E. fan art. Note that all artwork is preliminary and will probably change before we get to something we'd call a public release, but I think this shows the level of quality we can achieve with Mike and Jeff's help.

(A Linux release will be along eventually, but is a bit more work; but Linux users are encouraged to download one of the above archives and try building it themselves, using the free REALbasic Standard Edition.)
Here are some (possibly outdated) screen shots to give you a feel for what OpenMULE might look like. (Click the small images to enlarge.)
