Ryan Bryant, founder of Take Two Interactive, the company made more famous recently by its involvement with the Grand Theft Auto series by developer Rockstar Games, has resigned as chairman and director amid an investigation into accounting violations, according to the Associated Press.

Take Two once owned 19.9% of Bungie Software, and accepted the rights to the Myth and Oni franchises, in addition to licenses to use the Halo engine, in return for their shares when Microsoft bought Bungie and made Bungie Studios a part of Microsoft's Game Division.
