Should I buy Nascar the game 2011

It all depends if you want it for the multiplayer racing or season/career mode and single player racing. I have the game, but I personally do not care for it too much, because I like the online purpose of the game. I have it on Xbox, and there are many glitches in the game when you race online; from getting stuck in the track to bumping a car to a full second ahead of you at Daytona to cautions not being thrown when you spin or even flip to getting wrecked by drivers going backwards to laggy rooms when near full and drivers wrecking under caution or coming to the green flag when you are not in control...! If you see what I mean, the online is not too good.
On the other hand, the single player is definately fun, but tends to be easy, even on the hardest difficulty. No problems with lag or racing though, but drafting definately plays a key part in a positive and sometimes negative way.
I do not know if you should get it or not, but with what I've told you, you can choose from the facts! Hope this helps you!
