AC doesn't try to be a game in the same way PC2 does. Anyway, let me give you a piece of advice: Go into Custom Championships mode and enable a long practice session for the race weekend. Select every single car you want to drive "against" and choose at least two tracks (formal championship requirement). The practice session now provides an unscripted track day simulation where random fun will unfold as you encounter other cars out on the track. For example, you can try to match the pace of opponent cars or just mind your own business with the occasional traffic to navigate. No rules but loads of fun. I know that PC2 allows for something similar, but I think AC nails it better thanks to higher degree of AI awareness, opponent car customization and overall authentic feel. Of course, feel free to proceed onto qualifying and race sessions if the competitive element is what you're after. My point? AC may not be the typical racing game where the fun is presented in plain sight, but there's enough depth to find it with a bit of creativity. If you're finding AC graphics somewhat dull I'd also recommend experimenting with the cloud coverage options and setting time to either early morning or late afternoon. More eye candy this way.
