Midnight Club 2 does a great job on the Xbox. When it come to gameplay it's in the top of the racing category on microsoft's console.
The graphics aren't the best aside from the cars, but they're not bad either. Some lines could have been smoothed out. The cars are done perfect.
The Gameplay has plenty of fine points. Being able to race in three different cities, LA, Tokyo, and Paris, add to the enjoyment. Take Paris for example, being able to drive under the Eiffel Tower or through the Arc de Triomphe just makes you happy. Next there is the oppenent and pedestrian AI. They will never act the same, if you repeat a race they will act differently.
Unlocks are basically you go through the game and you'll get them. But, there is the arcade section that allows you to unlock each cities police car. Driving around in a police car and seeing the lights flash and hearing the sirens is all kinds of awesome.
