Polyphony Digital has always been very open about how their games sell. Similarly with Gran Turismo 5 Prologue. GT5P (the predecessor of Gran Turismo 5), has a total of 3,940,000 units sold. That is just a 'half' game. In total, the Gran Turismo series has sold more than 52.73 million units .It is a very popular series and will remain so!
Hopefully Gran Turismo 5 will break all records!
