Doom and Quake co-creator John Carmack has resigned from id Software, the company he co-founded in 1991, to concentrate full-time on his position as Chief Technology Officer at Oculus VR, the company behind the Oculus Rift technology.
Carmack was named CTO of Oculus VR back in August this year, but was previously doing double duty at both companies. id Software parent, Bethesda Softworks, had also stated that Carmack's work at id Software would be unaffected.
On Carmack's depature, id studio director Tim Willits stated:
"John Carmack, who has become interested in focusing on things other than game development at id, has resigned from the studio. John's work on id Tech 5 and the technology for the current development work at id is complete, and his departure will not affect any current projects. We are fortunate to have a brilliant group of programmers at id who worked with John and will carry on id's tradition of making great games with cutting-edge technology. As colleagues of John for many years, we wish him well."
Carmack offered his own comment through Twitter, saying, "I wanted to remain a technical adviser for Id, but it just didn't work out. Probably for the best, as the divided focus was challenging."
Carmack is the last of the original four id Software co-founders to leave the company, which also included Tom Hall, John Romero, and Adrian Carmack. Earlier this year, the company also lost studio president Todd Hollenshead, who had been part of the company since 1996 and served as its CEO until its 2009 acquisition by Bethesda.
