Same!
I just got to the start of Wall Market last night, and figured I'd stop there as it's one of my favourite parts of the original and I wanted to give it plenty of time.
So far I've loved it. I was worried that given how much they're expanding on the story, and given that there were a bunch of sequels/prequels/spin-offs already, they might end up fucking up parts of the story I liked in order to make all of that better fit together, but so far it feels note-perfect. It feels more "Rogue One" than "Phantom Menace" in that rather than adding superfluous elements to the story, it's expanding on parts we already know but went under-explored and, so far, while a few things have been moved around and given a little more time, it doesn't feel like there's anything that directly contradicts or undermines how I expected the characters to behave.
In terms of fleshing out the story, I like that it establishes AVALANCHE (is it not ALL CAPS any more?) as being a bigger entity than just five people, and better contextualises the world they exist in, as well as showing the people of Midgar as being either opposed to or broadly sympathetic to them as a bit of a spectrum, rather than them just categorically being the good guys. Given that it's post-9/11 world, it was inevitable that playing as a literal terrorist organisation had to be painted with a few more shades of grey, and equally it's unsurprising that the ecological side of the story (and the nuances of people's role therein) has been given a bit more scope too.
Character-wise, I really like this version of Cloud, and I love that Biggs, Wedge and Jessie have been fleshed out a lot more, in terms of actual "screen time" but also allusions to their backstory. I always thought they got a bad shake of it. Jessie, in particular, was a character I always liked in the original, and is set up as a potential love interest early, but is basically forgotten about before long and it just becomes Aerith or Tifa, so I'm glad to see her really become more of a focal point for a time here.
Aerith is one I'm really happy with how she comes across, too. There always seems to be a temptation to paint Aerith as a purer-than-pure goddess figure, forgetting that aside from all that she's a slum-dwelling, hobnail boot and leather jacket wearing, sarcastic free spirit. They manage to capture all of that, while also feeling like she has a level of self-awareness or understanding of the plot beyond what she's letting on, that makes her feel like something more than she lets on - which is exactly the vibe she should have.
So far, I love it. I have so many thoughts, but I'm going to try and save them 'til the end.
EDIT: I forgot to mention that Midgar is visually near perfect, and the game is absolutely stunning. I'm far from a graphics guy - I can barely tell the difference between HD and SD, and very few of my favourite games are those you'd consider graphical masterpieces - but what I do really appreciate is attention to detail, and good set-pieces. You can have the best graphics in the world, but if you use them on nothing but dull grey scenery and wooden crates, it's meaningless. If you use it to flesh out a world, and create breathtaking landscapes, then I'm interested. And that's what this game has - every time I'm in a new area I feel like I need to stop for a moment to rotate the camera and just soak it all in, from getting a view of what the streets of Midgar look like all the way down to the fine detail of the characters' materia actually being visibly slotted into their weapons. I can't wait to see how this game/franchise tackles some of the locations to come.
On top of that, the level design feels rational. Even when it falls into the latter day Final Fantasy trap of practically every new location basically being one long corridor, it looks great, and feels somewhat sensible - there are rarely cartoonish traps that kill your suspension of disbelief by making you think, "well come on, why would Shinra have even built that", or routes from A to B that make no sense when you try and visualise them as something that would be traversed by real people in their day-to-day lives. They've gone to some effort to make it feel logical, in a way the original perhaps didn't always.
