Nascar doesn't mean much to those outside North America, especially if you have never see Days of Thunder. For those not familiar with this branch of motor racing, it mostly involves driving laps of an oval track with banked corners. And that is pretty much what you get in the game, which doesn't give you much to work with.
Graphically, yes, this is presented in glorious HD (but not to 1080p) on the PS3 in Dolby Digital etc, etc, but it's difficult to get past the tedium of actually playing the game. Trying to break out and hit a relatively normal bendy track (which you can do) only reinforces just how serious this game is about being a sim – you just can't turn the corners and unless you have the patience of a saint, you'll be flogging this on eBay before you can say Daytona.
EA do some great sports games – this isn't one of them.
