I've been playing Need for Speed World Online for a while. They're slowly releasing cars into World. So far there over 50 vehicles to choose from. I can see where this series is going however the customzation is very limited as players will find there hardly anything to choose from compared to Underground 1 and 2. This is something players wanted the most. Upgrading your vehicles with performance is confusing and you cannot sell the parts. I think it's because as an MMO, it's all universial and trying to be stats based however that means once the part it's installed, it there forever. If it's gets taken out, it's get sold instead and cannot be fitted into a different vehicle.

Recently they've added a vehicle with police lights, I think they're going to apply this with all the vehicles, so players can have them aswell or a Cops and Robbers mode could be underway, however this is just an opinion I have.
