Tight Need for Speed game..
Electronics Arts also added Porsches and Lamborghinis in the game which are also fully customizable. As far as the A.I. goes its challenging enough nothing hard but it may take you a couple times to complete a challenge. I personally found the A.I. annoying since if it passes you it slows down like they made it so the A.I. never gets a insane lead over you.
The graphics in NFS:MW are pretty good nothing amazing but their decent for a launch title specially on a HDTV. The online multiplayer is pretty decent it allows you to join ranked or player (unranked) matches and you can have up to 4 people in a game.
In the end, Need for Speed: Most Wanted is a decent racing game and probably is the best in the Need for Speed series. The game is definetly a must rent or even a must buy if your a fan of the series.
