I really hated this game for like the first half. Other than the sweet madagascar chase scene from e3 I didn't find much that I liked and it did start really slow like a bunch of folks mentioned. I think I started enjoying it more when Elena came back in to the picture. She's a good character with a really good VA behind her and the relationship/banter with her and Drake was solid. all of the acting was really impressive actually.
so yeah, probably around chapter 10 or so is when I started getting interested. it just took forever to get there. the story was fine. I actually missed the ridiculous supernatural nonsense from the other uc games I played - I kept waiting for it and waiting for it and was vastly disappointed. I think it really made the game feel like it was dragging since there was literally one enemy (shoreline) for the _entire_ game and they had like 4 visual variations. I know that's par for the course, but some ghost pirates or something would've been a nice wacky change. or anything.
It looks pretty enough, but when I sat there and stared at it as I was moving around I couldn't help but think 'assassins creed does this better' - whenever I'd see Drake's arm try to brush up against a wall or person or other solid object and he misses by a foot I'm just a bit more appreciative of that new AC engine. For all their foibles, ubisoft has really honed the mechanics and interaction of that game. it feels like the main character in an AC game is actually interacting with the world they're in unlike uncharted 4 which honestly felt like programmers were trying to create an illusion of interacting with the world. the excessively weird partner AI didn't help this either - they could run directly in front of bad guys without alerting them (probably for fairness reasons, I get that) and at least on crushing they almost literally can't kill anything. in avery's mansion I let elena sit there and shoot point blank at the last guy in the room for 5 minutes and he wouldn't fall down. I think she actually put 100 bullets in him.
as far as the Crushing difficulty it wasn't that bad - I don't know what happened to simm/vig, but for some reason I breezed through chapter 20 with barely any deaths at all. it was downright fun - I really got a kick out of the long underground cave after Avery's mansion with waves of dudes coming through. the end boss fight with the quasi qte swordfight was absolutely

ing awful though - probably 100+ deaths and took me two hours. too bad, because the actual visuals in that room are probably some of the best I've seen. it was definitely a mistake to start on crushing though. the repeat deaths really destroyed the flow of some of the levels and made the swordfight feel so bloody anticlimactic that I was just glad it was over. everyone that played it on a lower difficulty first and then used bonuses for crushing were smart.
the ending is great. I don't know if it's what fans of the series were hoping for (I wouldn't say that I'm a dyed in the wool uncharted fan) but I loved it. it had just the right amount of wrap-up and happy ending to make it feel like they could close the series out. and the transition to the epilogue surprised me. also, the Drake house is rad.
So, good game. I'm glad I played it. The ending, the nutty firefight underground and the madagascar chase were the highlights for me. I'll be curious to see what they pull together for tlou2.
