IGN.com has reviewed Uncharted 3 and given it....
A Perfect 10.
It's VERY rare that they give a game a Perfect 10. They actually gave it 10s in every category (Presentation, Graphics, Sound, Gameplay, Lasting Appeal).
From the review:
IGN defines a 10.0 -- a masterpiece -- as "the pinnacle of gaming". A masterpiece may not be flawless, but it is so exceptional that it is hard to imagine a game being better. That's Uncharted 3: Drake's Deception. From start to finish, single player, multiplayer, this game sings. The characters, the graphics, the sound, the story - they're all top notch. If you're willing to skip Uncharted 3, be prepared to miss one of gaming's finest moments.
I think I may have to push my sick day back to the day after Uncharted 3 is released.
