Got Uncharted 1, beat it. 6.5/10
Got Uncharted 2, beat it. 7.5/10
I would have enjoyed these games more if there was less shooting, and more problem/puzzle solving.
I liked the first Uncharted better than the second, mainly because there was more believability to the environments. They did a pretty decent job of making the environments interesting while working the Prince of Persia-style puzzle platformer bits in relatively seamlessly. In Uncharted 2, the environmental design seldom made any sense except that it would be interesting for a lone monkey-man to swing through one time. They weren't even pretending to be logical designs, which severely hurts the suspension of disbelief.
This is the same problem a lot of second rate Indiana Jones-knockoff adventure movies run into. There are crazy temples/secret passageways/whatever else that clearly have no purpose, could NEVER have been used for anything (never mind how they were built in the first place) at any point in time, and were blatantly designed for this one character to take an improbable course of actions through just this one time.
That feeling hit me full-on around the Himalayan temple in Uncharted 2, and from that point I had trouble maintaining enough interest to even finish the game, because I was too distracted by the backgrounds.
And yeah, I know most games have totally unrealistic level designs; that's part of what makes those levels interesting and challenging to play through. But part of what I really liked about the first Uncharted was how it had taken these PoP-style elements and woven them into something that actually made *sense* as an environment (most of the time, at least), which really helped bolster its cinematic feel.
