Midnight club 3: DUB was in my mind a very "average racer". Allthough it was far from a bad title it was so typical it was sort of dated feeling. With other titles like Burnout 3 and Need for Speed this game seems kind of useless and not worth owning.
There is one exception to my preveous remarks, and thats that multiplayer can by very entertaining. With games like tag and just plain exhibition races you can find yourself racing for large periods of time.
So far and large Midnight Club 3 isn't in my mind a must but can be if you either A) are a die hard fan of racing games or B) are looking for a good racing multiplayer expirience.
