Yet another game that has more interesting platforming/shooting components than Uncharted, and did it before that.
*hunts for youtube vid*
Don't, you'll just make yourself look like an ignorant twit. Crackdown had a moveset with all the finess of juiced up 2d Mario. It worked beautifully, but it was nothing interesting about it. And the shooting and overall combat had all the complexity of a kefir shit. Fun, but in the absolutely most primal, Serious Sam sense.
As for Crackdown 2, they'd have to fix some major issues. Get gangs in that level up with the character, even if that means giving them super-human powers. Bosses, the game needs bosses, and not just the type with extra armor and health. There are other things, but those are pretty critical.
