Well, this should be a simple BiiF.
It's more of the same, but a ltitle better looking and a little crazier. New side missions with only 6 levels of each instead of 8 and the addition of motorcycles are nice. There doesn't seem to be a talk radio station anymore unfortunately. Lots of fun though. Online players are still 90% gangsta-wannabe mouthbreathers.
I'd sum it up this way.
Since I answered yes to the first two questions, my answer is Buy It.
