Realms of Despair
Realms of Despair has been my favorite MUD for almost 6 years now, but recently it just went through the roof.
A lot of new code has been ported, and the world has been remade almost completly. Everything has just improved 100% with the new "port" as it is called, a thing that has been in the works for 4 years or more.
Hence, if you previously left RoD because of a lack of updates, now you know why, and I urge you to check it out again, cause it is a brand new place, expanding way beyond what it once was.
For new players, hearing previous complains about it being unfriendly to them, well perhaps that has been true, but now days everyone is a newbie with all the changes, hence now would be perfect time to get into the most addicitive realm in the world of muds.
I shall be there to greet you at your arrival.
