I didn't see a MUD echo, so I hope it is OK to talk about MUDs here. I am   
   currently designing a MUD from scratch. I have no code yet, but rather writing   
   down all the different use cases and features I want in the game. Basically I   
   want to be able to use the mud engine to create any kind of text based   
   adventure.   
      
   What are the coolest features you have ever seen in a MUD?
