This game is what Uncharted 3 should've been..
Uncharted 2 was such an improvement over 1, even though I really liked 1. I know it wasn't that popular before 2 came out, but I liked the journey, the characters, the story, the movie feel of it, Drake was like Han Solo almost, kinda cocky etc. Anyways then 2 added so much more to the series... the levels, story, characters everything. Then 3 came out and apparently I am in the minority, although I really do not get why, but it wasn't that good, I mean as a game it was great, but next installment, it could've done more and better, it had nothing new. I mean there's the scene where he's nearly dying, dehydrated and then boom, he's all good to go. they did the history part which was great, but they should've done more.
Tomb Raider did that, they made it more realistic, the character reacting to everything around her, pushing her hands against rocks when she walks past it, reacting to pain more etc etc. Hopefully for Uncharted 4 they'll do something unique too. Anyways both great series in any case.
