Uncharted is WAY more frustrating than Last of Us. There are times when you're just completely screwed and nothing is going to save you except luck. No freakin' clue how I beat the first game on Crushing, but it was a terrible experience. Outside of one or two parts in Last of Us (freakin' Winter section...), hard mode wasn't that bad. The biggest issue I have is the enemies become bullet sponges, but since I use stealth most of the time it's not really an issue. The problem gets out of control on the forced action sections, which is the reason I finally quit. Survival mode takes away the noise vision, which is a no go for me. You really need that skill to play with their given level design, so I'm sure it would just piss me off.
Also, I died about a hundred times playing Uncharted 2. Just throwing that out there in case people thought I was showing off how good I am at games or something. I'm not really good at games. I'm just persistent. I still throw a controller every once in a while.
