GT6 looks great for PS3. Hopefully someone can make a nice montage video with new replays to do this game justice. Can barely find a nice video. This is the only good one I could find.
Pcars is a good comparision rather than Forza5, which is least impressive on new consoles TBH. Pcars not as beautiful as DC but has more than 12cars on track, night racing, dynamic day/night, weather system, car models look nice and still do 60fps. I was sure it was going to be 30fps like shift, F1 games on PS3. Considering everything that is pretty good
I do not think it is possible or it matters to have full nascar grid on track. 16 is fine as long as details are top notch. I guess they can go for 24 cars on track. Better for long and endurance races.
