I've played through the first three games recently (almost done with Uncharted 3), and I have to say, the gameplay is decent but had its weird moments. Sometimes, I die while jumping from like 15-20 ft, which is kinda weird. I don't mind getting damaged, but automatic death? Coverage is a bit wonky at times as there are moments where I don't get to a cover in a position I want to be in. There are also some weird moments where I tried to move Nathan and he suddenly makes an unintentional abrupt movement. It didn't always feel natural.
I will say this, though, the action scenes are pretty entertaining and its fun seeing the characters interact with one another, even if the plot is the typical B-movie, Indiana Jones-type. I don't mind since I'm a fan of Indiana Jones so I don't always take the plot seriously. If its crazy to see a refrigerator survive an atomic bomb, then its also crazy to see Nathan Drake (as a kid and as an adult) able to climb the way he does and that's fine with me,
