I also think the graphics are slightly worse than Uncharted 3, there are a lot of muddy texures, clipping errors and weird lightning.
Right now I am 70% through and I would rate this game a 8.7 because the story and the characters are very very good but in terms of gameplay, AI and graphics this game comes nowhere close to what has been shown beforehand. I hope the E3 TLOU is out the somewhere on some high spec PC. THAT game would have deserved the praise but the one that is on PS3 right now just doesn't cut it.
I can understand that. I never had a big issue but I understand your opinion. And the parts you are talking about at the end I elieve they did that on purpose to make it more cinematic with him closing the coors and blocking them off. I was able to sneak by everybody and then make a break for it to the door XD haha
