PlayStation LifeStyle:
"The Gran Turismo series debuted in late 1997 with the original PlayStation 1 game, Gran Turismo. The game sported an unprecedented 180 cars, 11 race tracks, and high-quality visuals. It was quickly sold out in Japan, and developer Polyphony Digital raced to produce both North American and European versions of the game. The original Gran Turismo was very well-received not only due to the quantity in the game but also due to the quality racing simulation gameplay. Eventually, Gran Turismo would become the highest-selling game ever on the PlayStation 1 platform."
