Don't you mind, that giving some name to the new world is trivial? If y examine the history of culture of any nation, you would realize that the translation of the name of auto-called territory occupied by this nation means either "the land" or "this place" or "the place where we live".
On my opinion, calling the game platform just "The Land" will introduce some rational mystification concept, instead of some stereotyped name as "Arkania/Alkaria/Asmodea..etc". I think it will be a good marketing decision.
If you wanna "justonemorepatheticname" open the World of Warcraft server list and choose any.
