Arcade ? It's pretty hardcore if you turn of the driving assists. Try racing without them with the BMW 320i, on serious or higher. Good lucking coming in third or better ... Make sure you have the lock head cam box checked ...
I like the game a lot, definately a must have, simply because I love racing. It also looks great, better then DiRT I bet, but it runs better for some reason, better FPS. In DiRT I noticed slowdowns with a lot of opponents, no such thing now though. Drifting is pretty nice as well, not nearly as arcade like as in ProStreet. Damage system is also pretty neat.
