Realms of Kaos

Realms of Kaos (commonly abbreviated to RoK) is a text-based massively multiplayer online role-playing game that was released in 1996 by developer and “DungeonMaster” Lance Hoskins under the name Up All Night Entertainment, or UAN. RoK is a unique mix of text based action and graphical interface using a turn-based system. The key difference between RoK and other MUDs is the fact that RoK uses its own client with original graphics to connect to the server instead of telnet or a MUD client such as zMUD. Also as a graphical MUD, it is probably the most popular of its kind and has inspired many similar games which are linked below.
