I just bought God of War III yesterday and goddamn is that game epic.
The very first boss battle pits you against Poseidon's giant water horse on top of Gaia, the titan, while climbing up Mount Olympus.
Every single thing about the game is huge and the graphics are better than Uncharted 2.
Sure it's a button masher, but it's a pretty *crag*ing insane button masher.
