The ninth(!) installment in the popular racing series Gran Turismo, Gran Turismo 5, has shipped over 5.5 million copies worldwide, according to Sony.  Overall, the entire GT series has sold more than 60 million copies since the launch of the orginal Gran Turismo was released in 1997.

Gran Turismo, with its 1000 licensed cars, real-life tracks, well-worked-out physics and ton of features has essentially defined the racing genre for years, so much so that it makes it all but impossible for anyone to compete on the PlayStation system. Sure, 360 users get Forza, but it's almost like GT 5 is the entire "real racing" genre. Sure, there's a bunch arcade-style drivers, but, for the PS3, there's essentially only one game, and that's likely to continue.

I'm an unapologetic fanboy of the latest Gran Turismo game, but I understand a lot of people don't feel the same way I do. How about you? Are you into the real racing simulator?
