Rockstar was born from a developer known as DMA DESIGN. They originally developed Uniracers for the SNES for Nintendo. They were asked to work with Nintendo on future projects as well including a cancelled Kirby title and as part of the infamous Nintendo Dream Team (A group of developers selected to showcase the N64). Their title released as Body Harvest on the N64 and was a free-roaming 3D game that allowed you to ride around in various vehicles found in the game (many people see it as a spiritual successor to the GTA series). They parted ways when Sony proved a dominant force in the industry with the two most successful home consoles ever....
