RockStar North's predecessor DMA Design was founded in 1988 in Dundee, Scotland.
DMA Design became part of the Rockstar group of companies in 1999.
Known previously for it's top-down Grand Theft Auto games, 2001's Grand Theft Auto III brought the series into 3D. It became the PlayStation 2's biggest system seller in both the U.S. and Europe; Sony, realising that the game was a sure-fire success, paid Rockstar to keep it a PS2 exclusive for some time.
DMA Design was renamed "Rockstar North" in early 2002. That same year Grand Theft Auto: Vice City was released, which retained the engine and core gameplay of GTA3 while adding a number of refinements and a roster of top Hollywood voice talent.
The developer's next release, Manhunt, was released for the PS2 in November 2003 amidst a media frenzy surrounding the game's extremely violent nature. Rockstar North released Grand Theft Auto: San Andreas for the PS2 in October 2004, and ports to Xbox and PC followed in 2005.
The studio has completed its latest title, Grand Theft Auto IV, which was released on the Xbox 360 and PlayStation 3 on April 29, 2008, and marked the debut of the GTA franchise on the seventh-generation of video game consoles.
GTA IV is Rockstar North's biggest success yet, receiving universally rave reviews and becoming one of the most critically acclaimed video games of all time.
