What strikes me the most from your post is that you find crushing the easiest of the series. WHAT ARE YOU TALKING ABOUT?
Hats off to you if you did it legit, but it's definitely the most crushing difficulty of the series imo
Yeah if you check my trophies you can see I got the crushing trophy on my first playthrough. No infinite ammo cheats. Was kind of dissapointed they allowed those cheats. Minimizes the platinum a bit. That would have made it a sinch with the one shot pistol, grenade or rocket launcher w/ auto aim...
I did find Uncharted 4 crushing easy, with the exception of 3-4 checkpoints. The first stealth area in the jungle where the enemy comments about seeing movement in the bushes, 2nd was inside the building where you try to push past the door blockade and get ambushed, and that chapter 20 checkpoint. Good lord that first chapter 20 checkpoint took at least 2-3 hours of tries. And the very last checkpoint on the final chapter I had quite a few deaths until I got the timing down.
Perhaps I found it mostly easy due to all my gaming experience with the Uncharted series. Originally I really struggled with crushing difficulty on Uncharted 1 when the game first came out. By the time I played it again when trophies were patched in I was surprised to find I had a much easier time. Knowing what to expect certainly helped. Uncharted 2 & 3 had a few hard parts as well: the train, final boss on 2 without taking advantage of the glitch, and fire demons in 3.
Most recently when I played the Uncharted Collection on crushing I breezed through all of them with very few deaths that weren't intentional for grinding out weapon trophies. Need to still try the grounded mode on those. Heard its not bad.
I guess your right about Uncharted 4 being the hardest. When I compare playing Uncharted 4 to replaying the Uncharted Collection, Uncharted 4 was harder because those 4 checkpoints gave me a harder time than anything while replaying 1-3. I guess I was just surprised at how easy the rest of Uncharted 4 was. If I compare my first Uncharted 4 playthrough to my first Uncharted 1 crushing playthough then Uncharted 1 gave me hardest time. For me I think Uncharted 2 was also more difficult than Uncharted 4 the first time.
