I've got to Reno and Rude, and they're not awful. Rude's the least noticeable. Other than Sephiroth, I haven't really been bothered by any voice changes. While it's not the old actor, I feel like the dude doing Barrett is perfect. Cloud sounds close enough to the original, and again, no one else has really bothered me.
Other than that, I pretty much agree with everything here. Reactor 5's design gave me a little bit of XV vibes as rooms are kinda recycled, but it feels pretty negligible in the grand scheme.
I think one of the things I like most is for the most part, no story point, small scenario quirk, or notable bits of dialogue have been culled. Like just when I'm thinking, "Aww, they must have retconned this out," it comes around and makes sense. I've only found one thing of that nature that's bothered me so far in the Sector 5 Slums, but I get why they did it. Spoilered just in case:
Ditto on all the small details, by the way. The first night, I found myself just taking extra time to read all the flyers and take in the surroundings. I was floored when it hit me that I could move the camera up and actually see the plate. I also love the conversations from NPCs. I feel like it does a much better job at painting a picture of life in the slums, and how Avalanche's actions are affecting the townspeople.
I just got to the Wall Market last night. Getting ready to dive back in.
