Fairly decent actually. Instead of trying to copy Gran Turismo the developers opted to replicate the sensation of being on the edge of control. The cockpit camera is incredible and quite frankly, the only way to play Shift because it genuinely enhances the experience. Unfortunately the handling doesn't feel all that good and most cars will require tuning to not oversteer horribly and even then every once in a while your car will either start jumping for no reason or behave unpredictably. My biggest issue with Shift stems from its use of the Driving Line. The game encourages always following the line, turning it off puts you at a big disadvantage and makes the already tail-happy vehicles even harder to control. It made me feel like I never actually got good at driving, but merely at following the displayed line.

PSP: One of the worst racing games I've ever played, plays like all the previous shitty NfS games on the PSP but it's somehow even worse. I hate it with all my hate.

PS2: Buggy and unfinished trash reusing Carbon and MW assets. Can be fun whenever the game isn't falling apart, which is rarely.

PC/PS3: I've already finished Undercover multiple times and remembered it somewhat fondly. Replaying it now I was expecting to find the game mediocre but playable, however to my surprise after a few hours I genuinely couldn't stomach playing it any further. The physics are clearly unfinished, the game looks disgusting, the car roster is straight up bizarre, the attempt at creating a story is pathetic and intrusive thanks to its unskipable cutscenes. The only thing Undercover did right is its music, particularly the selection of tracks used in the Garage and on the Map Screen, both of which excellent.
