I could have sworn somebody replaced my disk with Need for Speed Underground 2.

User Rating: 7.5 | Need for Speed Carbon X360
I finished this game yesterday and altogether it took me 3 days (about 5 hours a day). I found that this game was much shorter than all the previous games in the Need for Speed series and I was very disapointed to see that they had taken drag races out of the game. Aside from that, the visuals are good, the gameplay is fair except it can be quite difficult to win races and unlock new parts after defeating a boss (After defeating Angie I nearly gave up playing)

Need for Speed Carbon is also very similar to Need for Speed Underground 2; It is always night time, one part of Carbon Canyon is a big city, the other is a mountain, the airport and the fact that you can challenge racers that you see in free roam. Also Need for Speed Carbon brings in a new drift system. I found that this drift system can be extremely frustrating to pick up, but after you've got the hang of it, it's not too bad.

Overall Need for Speed Carbon gets a 7.5 because of the shortness, for removing drag races from the game and the fact that it is so similar to Need for Speed Underground 2.
