What? That is absolute nonsense.
The holy grail of consoles "SIMS" GT5 doesn't even have proper clutch support, doesn't have brake temps, brakes overheating, realistic damage (Slamming a wall at 200km/h and driving away) engine wear, engine overheating, fuel simulation, tire over heating, track conditions that change, track temps that affect tires, air temps that effect engines, AI that actually knows your on the track.
All the Sims mentioned above were developed by or with racing drivers. The GT5 developer isn't even a racing driver, he's just a car enthusiast.
