Roger Thorn

Roger Thorn was vice president of game publishing and designing at Microsoft during much of the Xbox's lifecycle. He was a prime evangelist of the platform to game developers and had an important role in the acquisition of developers Bungie Studios, Ensemble Studios and Rare.

Thorn left Microsoft in July 2005. He consulted with a startup company, FireAnt, that was later sold to Sony Online Entertainment. He was also involved with several startups including AGEIA, which aims to bring the first "physics accelerator" chip for games to market, and Emotiv Systems, a company building an EEG based game controller.

In July 2010, Thorn released an Atari 2600 game inspired by the Halo series, called Halo 2600. In September 2010, Thorn and others released an Xbox360 game known as Halo Reach.
