Uncharted 2 is the best one. Let's be honest here! I know you all agree with me! In this video I spend (almost) 15 minutes with the new remastered version and it still looks incredible.
I especially love the opening of Uncharted 2 -- the whole climbing out of the train sequence. It's just unique, interesting, and serves as a super cool intro/tutorial section. I honestly feel like I could replay that over and over!
A quick note (and apology): there are some issues with the sound, especially during the cut-scenes. I'm a bit of a noob at this video capture business. Hopefully I'll iron out all my issues soon! Thanks for your patience!
