This category is for general information concerned with online games which are known as 'Muds' or 'MUDs' (including all the different types of server/codebase which exist - MUSH, Diku, LP, etc). These games can be played via a telnet or Java application, or with one of the many 'MUD clients' which are available (mostly free of charge), online.
