On RPG like games (curently only play ADOM and it's not a MMO) I use Gulfd'An even if it is close to Gandulf I still think it's original. I also used Oryp Cainam and Pocket change man in various books. Once in a while I change my name on blockland (to things like G.buses, Lt. Thorvald, Steveil) but I allways returned to Lt. Chub Chub
