There seems to be one thing where KZ2 really fails. Now, from the reviews, and videos, what we have here is a game whose developer was very smart, in the sense that they picked what they liked best about other great franchises, and made a game around it. Sure, they have their own spin on the "feel" of the controls, and motion, but that's superficial, that's icing on the cake, not the cake itself.
Now that ain't bad, it just means that the developers decided to focus on a polished and "safe" product. But there's one thing that they missed, they try to emulate Gears of War 2, in the whole tough guys cursing, but they completely miss it.
In Gears, they sound funny, and cool because it's all very bad boys 2iish. Here it's not, it just tries too hard.
