Edit: Denied by NCSoft, but then they would say that.
The rumour-mill over at Joystiq is grinding up some vital seeds of information from the Texas MMO scene. It looks like NCSoft's main North America office might be in trouble, which means that Dungeon Runners and Tabula Rasa are on dangerous ground.
Future development of Tabula Rasa will reportedly be handed over to Seattle-based Guild Wars creator Arena.net, with Massively reporting that the title may meet a similar fate as Dungeon Runners if it "fails to turn the tide of subscribers and expectations." It has also learned that any future collaboration between NCsoft and Tabula Rasa principals Richard and Robert Garriot will be "limited in scope," due to a souring of relations with the Korean management team over their title's lackluster performance.
It sure is a shame TR wasn't much fun. Dungeon Runners is a laff though, and free.
