Wow just got done finishing Uncharted 3 from the PS Plus thing. That section where you walk into the Atlantis of the Sands is incredible. It literally took my breath away. Such an incredible game.
I have to say after playing both the Last of Us and Uncharted 3, I think Uncharted 3 looks a bit better. I think it's just that I prefer the art style of Uncharted 3. The Last of Us is more real and gritty.
