By moving away from its arcade roots, ProStreet is awkwardly straddling the gap between Need For Speed and Forza, having a firm foothold in neither, thus screwing itself over by chasing what it perceives to be the most popular kind of racing game at this point in time.
There are some very definite problems. Playing this with an Xbox 360 controller makes it impossible to drive in a straight line, due to the lack of a thumbstick dead zone (making drag races a pain).
Also, the driving model has been almost completely redesigned to dispense with the series' usual arcade handling, making the game far less satisfying to play. It lacks the grit and excitement of a simulation, and it lacks the stupid fun of an arcade racer. It doesn't even have police chases.
The game is composed of a series of Race Days and Showdowns, each broken into various racing events: standard 'lots of cars go round' races, drag races, time trials and drift races.
These events require you to tune your car to suit the particular type of race - and these setups can then be saved as blueprints and traded online, if you enjoy doing pointless, ridiculous things like that. I, personally, throw my blueprints off a bridge, if it's all the same to you, EA.
Things pick up when the opponents eventually start to become challenging, and the tracks a bit more varied, but the game gets off to a rough start and overall feels a bit too easy and slow-paced.
Sure, there are far worse driving games than this one, but in terms of the Need For Speed series, this is a dud note. If you want realism go for GTR2, if you want arcade go for NFS: Most Wanted, and if you want to play a confused, bipolar racer that's lost its way in the big bold world of scary next-generation racing titles, ProStreet won't let you down.
