Please do not take the iPhone version of Undercover into consideration, this is only for the console/PC versions of the Need for Speed games. Also, please compare only within platforms, so don't compare (for example) the 360 version of Undercover to the PC version of Most Wanted.
most wanted is the best f**k the rest =) no just kidding i really like underground 2+1 and ofc hot pursuit undercover isnt bad but nearly the same as mw and carbon
I have only played underground and most wanted but most wanted was certainly a favorite of mine. The cop chases are a heck of a lot of fun.
most wanted was the peak of the series by far but then it just went down since then. Shift has recovered it but the series has always been about the street racing rather than the track.
Most wanted was incredible, carbon wasn't bad but it could have been a lot better, and then from prostreet it went downhill. Played the shift demo and actually was impressed, but not enough to buy it with all the other fantastic games coming out soon. And I do feel bad for shift cuz it's prob gonna be one of the worst selling nfs games of recent memory just cause the last few have sucked so bad and cuz both consoles have their own exclusive racer coming out (forza 3, gt 5). It hit a million copies but its not gonna go anywhere near undercover's like 4 or 5 million or prostreets like 8 million
