"The graphical line separating video games and real life has been getting thinner and thinner with each passing console generation, and the Gran Turismo series always seems to be the one leading the charge.
Harnessing the PlayStation 3's graphical power, Gran Turismo 5 features the most realistic graphics to date. So real, in fact, that many people can't tell the difference between an image from GT5 and its real-life counterpart. To prove this, a Neo GAF forum member created a quiz featuring screens from GT5 and GT5 Prologue that will have you staring inches away from your monitor trying to discern the difference."
