I've played game really similar I don't see how its any better than any of those games don't get me wrong id still play it but its a dude with a gun that has a chainsaw taped to the end of it. While God of War is a Spartan fighting Greek mythology and taking everything from the Undead Barbarian's hammer to a weapon forged from the Olympian metal and even some of the god's weapons like the Blade of Olympus on top of this the graphics are just wow.
Like I said. You have to play it to know it. And I have to admit the graphics are granted way better than Gears, but ours is just badass. God of War is just swinging guys around with your swords. Gears is so much more brutal, fatal, and gruesome than God of War.
