Indeed, the fact this wasn´t in GT5/GT6 upset me alot. Specially in GT5, I mean, you had 24 hour long races and then you had nothing more than 12 cars (about a quarter of the real grid) and what was worse was that it would be composed by an Audi R8 (A GT3 Class car) A Viper or a Corvette (wich at the time were GT1 but have similar specs to GT2 compared to now) A Nissan R390 or a Mercedes CLK GTR and then it had LMP´s normally beeing a GT-ONE, the Pescarollo´s, a Bentley, the BMW V12LMR, the Audi R8 and the Peugeot. If you were an experienced driver, even though GT´5 competition is way harder than GT6´s you would lose all the fun in the race and the track would be empty, so it would basically resume to you doing laps arround the track for 24hours like it was a time trial, and you sometimes would have to overtake a car. If we had 46 driver grid´s and multi class, those events would get their fun back, and it would be like the real race, and if it was like that, then, I wouldn´t mind having 24 hour long races back... Now I see why PD turned the 24 hours of Le Mans into the 24 minutes of Le Mans...
