Worlds of Carnage started as a Diku based MUD in the early 90s. It has seen several generations of code improvement and addition and has close to 100 fully developed areas (not auto-generated ones, but honest to God someone worked on them areas…). It supports active multi-classing in a system that doesn't allow for blatantly overpowered combinations and it is a full-time PK MUD. New players are encouraged to start in either Elip (easier leveling) or Elkin (easier access to new user materials and trainers.)
Asgardian Nightmare has a long and successful history. Peaking at a
playerbase of as many as 30 players on at a time, this mud was a very
good mud.

But the mud was closed down for a while.After a long period of downtime
the mud is reopen again for players under a new look and with new Owners
and Immortals, and with a new site. Allow me to describe a little bit
this mud :

One of the most outstanding parts of our mud
is random item generation. It works like the items in Diablo 2, where an
item is assigned prefixes and suffixes that give it extra stat bonuses or
drawbacks.

With a huge number of prefixes and suffixes, as well as condition tags,
there are literally millions of possibilities for random items.
Builders are constantly working on new areas, so the mud is constantly
evolving. We offer three tiers of classes, with 21 third tier classes to
choose from, and the option to let your race evolve into one of many new
races as you gain experience.
