I want the first GRID that felt like actual racing with much better driving mechanics.
There're no vehicle upgrades in World Series Racing a.k.a Career Mode. Online racing feels like Destruction Derby. Be prepared to get annoyed. Need for Speed probably does it better. I have never been disappointed in a Codemasters game. I have the F1 2012 and I know these are two completely different types of games.
I am seriously considering trading this game after just owning it for a week. I'll try upgrades on the vehicles I own in Online Racing few more times. If it doesn't make things right, then I will trade it.
Oh and did I tell you how the Online Racing is buggy? Hopefully they are working on an update but your rival cars bounce in mid air and are rarely running on the road. Mostly hovering in front of you and teleporting from one place to another. No it's not lag.
