Richard Garriott will leave NCsoft to pursue "new interests" following his recent space mission.
"Many of you probably wonder what my plans are, now that I have achieved the lifelong dream of going to space," the Ultima and Tabula Rasa designer said.
"Well, that unforgettable experience has sparked some new interests that I would like to devote my time and resources to. As such, I am leaving NCsoft to pursue those interests."
Garriott paid tribute to his co-workers and the fans of his games, and thanked those that stuck around to play MMO Tabula Rasa after what he acknowledged was a "rough launch" period.
"I am very grateful to you loyal players for sticking around through what I think we can all honestly say was a rough launch. I thank the development team for pushing hard to get polish, updates and new content out every month since launch...a feat that I think is unusual in MMO development. They have a lot to be proud of.
"This news is difficult for me to deliver... It has been quite an unforgettable journey, one that I will treasure for the rest of my life."
A good as being a leading game designer sounds, we can only imagine how going into space (at a cost of around £17 million!) must open your eyes a little.
