I finally got my Platinum trophy for this game last week, and it was glorious. The fact that I have replayed this game 3 times and enjoyed it each time is astounding to me. I haven't done that with a game since ... well ... damn. Probably since God of War 2 (beating Titan Mode).
It really does say a lot about a game when, after beating it a 3rd time on the hardest difficulty and 100%-ing it, you still want to go back and play it again IMMEDATELY after finishing. Even the awful, awful, awful last boss couldn't ruin it.
And if you are playing this game for the first time, don't be an idiot like me. Remember to use blind fire every now and then. If you see a dude with a Magnum or a Laser Site camping out, blind fire 2 rounds to cause him to shift position then pop out and headshot him. It made Crushing so much easier (well, that and blind firing the shotgun whenever I could).
<3 Uncharted.
