Jesus Christ, it's really hard for you isn't it? It's not about violence. It's about how immature the medium is, that it still can't figure out action and violence, tension and adrenaline, without having to throw you into the middle of what is basically a 1 vs Army war.
It's not about violence or killing, it's about figuring out how to mature it to the point where you don't need to artificially bump it up by just throwing more numbers.
And are any of those games even close to having the same kind of context as Uncharted has?
Look at what you are saying. Go play Flower? Bangai-O spirits? How the hell do these games even relate to action games like Uncharted, Max Payne, GTA, etc.
Christ sakes, "You don't like Rambo? Go watch pokemon".
