Just finished this. Loved it. Felt a little too derivitive and not all the dialogue was top notch, but certainly better than any of the other games. Poor Del is still undercooked, but likeable but all the other characters went through a journey there. JD had a pretty good path there. Maybe a little rushed but it was fine, I think it's ok for side characters to grow a little off-screen.
Loved the way the third act looked. Destiny's Cosmodrome architecture and Mar's deserts combined into one gorgeous landscape and sick soviet era mega-architecture. But act 2 was the highlight with those freaky labs and an explanation for the whole Locust-swarm origin, relationship and motivations. Glad they finally stopped trying to be so fucking mysterious, but also greatful that the underlying lore made sense and paid off.
Skiff sequences felt like the boat sequences from God of War, not quite as good but still a decent way to have characters talk without the slow walking/craming it in cutscenes.
Still needs some stability/networking work on PC at least, though it runs and looks great on X1X as well. These devs are solid, can't wait to see what's next.
