There have been a few games (other than LOTRO) that gave Middle-earth-like names and biographies to some of the ringwraiths, but none of them are canon. Regardless, some of them have been accepted as pseudo-canon by the community, just as the names of the Blue and Green Wizards have been. I believe there is a card game that exists that gives names to all the ringwraiths. I'm not sure if it maintains Khamul or not.
