Who ever does not give this game a 9.5 or a 10 is completely not worth their opinion and obviously does not game enough.
Some will say that the vehicle controls were difficult to learn, and they were, but other than that trite complaint the game is spectacular. Beautiful soundtrack. This game makes Halo 3 look like some back room project. Seriously. With all the hype of Halo 3 you would have thought it to be AT LEAST as good as this. Nope. Not even close.
Sure they are two different styles of games, but halo 3 was, in my humble opinion, an over rated piece of junk and I almost feel embarrassed comparing the two.
Having such a great cast of characters to choose from, great upgrades, and sweet action sequences. My only complaint, if you could call it that, is that the economy / money system was almost pointless. Omni Gel was worth way more and you found all the weapons you needed to win. I only hope they come out with some expansion(s) for the game like in Oblivion. This game, in and of itself, makes owning a 360 and all the complications associated with that, worth it. Truly.
