No reason to post this in the AC topic as it's a credit to Uncharted, rather than a knock of AC.
I rented AC this afternoon, and while it does a lot of things well, it makes me realize how amazing Uncharted really is - I think I was really spoiled to go from R&C straight to Uncharted in terms of quality, because both of them were so top-notch.
To think people complain about any technical aspects of Uncharted is absolutely ridiculous in comparison to AC (well, at least the PS3 version, and if that's the case, I highly recommend the 360 version if you haven't already). Ridiculous amount of pop-in, tearing (every time I get a bird's eye view of an area when it pans around, it's almost dizzying), collision problems, framerate frequently dropping, 'interactive' cut-scenes that manage to frustrate you on their limitations rather than give you freedom (seriously, why in the fuck can I walk 3 steps before hitting an invisible wall?).
I give AC definite props for a lot of things (the whole scaling system is amazing, and makes me wish Uncharted had more interactive environments), but I guess I didn't appreciate Uncharted enough (technically) for how much it did... even with the little things like load times.
