A MUD is a text-based online role-playing game. It stands for Multi
User Dungeon, among other things.
It takes advantage of the
endorphin rush resulting from getting
XP,
levelling, and getting the
best eq.
For those of us with an
addictive personality, MUDs were the easiest thing to get addicted to on
the internet before
porn and
visual online rpgs such as
everquest became popular.
