Best known for huge hits such as GoldenEye 007 on the Nintendo 64 and Donkey Kong Country on the Super Nintendo, Rare’s long-standing creative partnership with Nintendo ended when the company was taken over in 2002 by Microsoft for £240m. The Stampers' stake was worth £82m.
Famous for its farmhouse headquarters in Twycross, Leicestershire, several start-ups have spun out of the game developer, including Free Radical Design and Playtonic Games.
