Pretty decent racing game, from all accounts its a big step up from RD1.
I picked it up yesterday, lots of fun. I haven't played the retail online yet but I did play the demo online a few times, and the netcode seems decent. May not support 20 cars online, but in the races I had with 5-8 other guys it was lag free for the most part.
Its not a hardcore sim, and when set to pro-sim mode its not arcadey either.
If you use a wheel, I would reduce the sensitivty in your controller properties, and then reduce saturation in game.
Contains a ton of different classes from Rally, to Aussie V8's, to Big trucks, to DTM, to vintage classics, to SVT Mustangs, to open wheelers and more.
Worth the purchase IMO
