Eh, most people's opinions are going to be more set once we all get our hands on the game, watch walkthroughs, see interviews, etc.
Just to be clear for myself, my concern, as much as I've been making the "Jenova-Heartless Darkside" joke, isn't really about any of that, actually. Just specific things (at this point, only two, really) that I've been able to watch and gain knowledge of. This development is fine to me in the sense that I had hoped, or was very prepared to believe, that there would be additions to this story because the team were in a position where they were well fully capable of doing so. If anything, I mostly agree with the point that these changes hasn't changed the complete makeup of the FFVII story in full, and most likely won't for the next parts. Even after this, it's still very much so identifiable as FFVII while also having new, creative spins on it for the sake of a story that is 20+ years old and had expansion to its constitution over that amount of years. There are things, changes and differences, that I'm actually well anticipating by the merit of its value to be placed in the Remake, after all.
Doesn't mean change is always good, whether observed on a level of impartial judgement or not, but overall, I wouldn't go with any claims that it isn't, like, FFVII anymore. I haven't played the game in full, true, but for what I have seen, the deviations aren't of THAT nature.
