While Microsoft has two large and still active racing brands in its portfolio, Sony only has Gran Turismo, and that's where the company is focusing all its attention.
It's obviously paying off. Gran Turismo Sport has sold over 12 million copies. But the series record holder remains Gran Turismo 3: A-Spec, which was purchased 14.89 million times, which to date has not been surpassed by any other part of the brand. But this year the situation may change.
According to NPD analysts, Gran Turismo 7 is the second-highest grossing game in the United States, which is truly impressive considering the game only came out two years ago. If sales momentum continues, GT7 will overtake Gran Turismo 3 to become Polyphony Digital's best-selling racing title in history.
