Grand Theft Auto V has chosen L.A. County as the basis for the fictional setting of Los Santos. The British and Scottish designers at Rockstar, the company behind Grand Theft Auto, have made immersive environments of LA's suburbs, the Nevada desert, upstate California and dozens of miles of underwater Pacific coast, a trademark. With forty-nine square miles of interactive territory, the map of G.T.A. V is bigger than all of Rockstar's previous open-world environments combined. It is also the largest interactive environment ever built for a video game.
