Really disappointing for me.
Nothing to do with the graphics. Hard to tell from my stream but they look beautiful.
For me, it's the complete lack of any innovation, change, evolution or progression. ND seem to have learned nothing from TLOU to take over to Uncharted 4, apart from a new reticule icon. 7 years on from the original, we still have the same formula of looking around (press triangle), climbing a bit, 'shit going to hell' and then a climactic sigh of relief. It's the same awkward animations, the same locations, the same enemies you kill in the same way and the same sloppy gunplay. It's more lushious and maybe a tad more open, but being able to duck under foliage now is not a progression that is worth 7 years of waiting.
In fact, for me it's almost a decline given the tone is all over the place. Every game they claim to be darker, more gritty, more emotionally damning, but it ends up completely at odds with Nolan North's little quips here and there and the attempts at humour.
At least Drake now has a brother who'll betray you that they've waited 7 years to tell us about?
There are games doing parts of what Uncharted did better, and there will soon be games (if you don't believe there already are) that do all of what Uncharted does better. It's staying the course and sailing on into irrelevance as it fails to renew or evolve. In fact, I'm pretty sure ND's own innovations and evolution in TLOU and whatever new projects are going to cannibalise Uncharted.
If you wanted more of the same, then there can be no complains. But for me, it's literally 'same shit, not-very-different island'. We can argue if it's a generational leap in graphics, but I can't see even sizable hop in gameplay after 7 years.
