Not a bad game, but no where near the 360's potential
The new universe thing is quite a good idea, although i didn't like the idea of being able to choose your routes at first, however, i think this can work.
I also have ridge racers on the PSP, and although the graphics aren't too shabby, technically, there aint a lot of difference between these and the PSP apart from the 360's graphics for this game have a hell of a lot more detail (the concept is still the same though)
If you are looking for fun and a quick laugh, buy this....
If you are looking for a technical racer that actually starts to resemble real life, buy Project Gotham Racing 3 (for the moment)
Not bad though.... although won't be buying the next one
