Its a very comprehensive MUD with fun places to explore, quests and interesting people. Check out the webpage at anguish.org or telnet to ancient.anguish.org 2222.

One thing about AA, is the long approval process new areas have to go through, to make sure that items are well described, balanced and in theme. It can be a rather tedius process, but I think the mud benefits from it. Visit it yourself and see!
