Codemasters is the largest independent video game developer and publisher in Europe, based in Leamington Spa, UK. It was founded in 1986 by British brothers David and Richard Darling after developing and selling games from their youth. One of Codemasters' biggest successes was Micro Machines in 1991. Though they regret not expanding more, Codemasters published popular game franchises and was one of the few British firms to self-publish, selling for £84 million in 2007.
