My stream quality sucked, so I couldn't fully judge the graphics on that, but I was originally disappointed that the climbing animations seemed to similar to other Uncharted games.
Once the combat started, though, I think the game looked great, and I let a little cheer out during the initial grapple segment
Can kinda see the Last of Us influence on the combat/stealth, and that's a really good thing.
I do still hope they make the traversal stuff a little harder, and make the adventuring parts have more options or at least make the one route less obvious (have more areas where you need to look around for the grapple points or something).
Overall, my most anticipated retail game of 2015 (narrowly beating Metal Gear, and only because I got to play a small chunk of that already).
