I found this game when looking for an active community like our own, but who race on PC. Some of you may already have watched this game without realising it - on Motors TV.
The graphics are nothing to write home about, and the vast majority of track you won't have heard of. Most tracks are based in Brazil, and the title car is the Brazilian version of V8s.
They are fantastic to drive, and the physics feel fantastic. The single player mode is very enjoyable, with better AI than I've raced against before.
There are plenty of other cars to drive, mostly open wheeler. My current favorite between the retro F1 (Senna era) and the Mistibushi Lancet Evos.
I'll leave this link here. I've personally never played Assetto Corsa, but from what I've seen around the Internet, the FFB on stock car extreme is better.
