An
open-source graphical MUD that, although a bit rough, is incredibly
addictive. It has a
client-server architecture. It's a combination of
Nethack and
Gauntlet. It has a
2D top-down view. Because it's open source, different rules can sometimes apply on different
servers.
Clients are available for
Windows,
Unix and
Java. Server is Unix only (for now).
