As of a few days ago, the Evennia MUD server has been re-licensedunder the BSD License. We feel like this will knock down another barrier for those considering running a game with Evennia. I can’t recommend this codebase enough for anyone who may have caught the MUD development itch (hey, they still exist!). Griatch has been doing an awesome job making improvements and building a community.
Evennia is an advanced Python+Django MUD server, with all sorts of goodies (like a web-based client). While the project has been going on for a number of years, the community has been growing a bit faster over the last year or two. We hope this will help continue that trend.
Feel free to stop by #evennia on FreeNode IRC to lurk, hang out, or ask questions.
