A lot of people dont know what they want and can't agree on anything.
This IS a brand new game, based on FF7 but re-imagined in a different light. Its not intended to be the original, do people have to say it a billion times?
They were never going to ever do a version of the game that was 1:1 with the source material, this was a pipe dream.
You keep parroting that line. That sounds like a hell of a lot more justification for changing course than it does the initial design idea. The fact of the matter is that they unveiled the game as a remake, and that in gaming, REMAKE has a certain meaning.
And it, in every successful case, does not mean turning Pokemon Gold into a third person action game, or Metroid 1 into an FPS. It means preserving the game's identity and then expanding on it. Not radically altering it.
So people that wanted it to stay turn based are just as justified in wishing the remake was faithful gameplay wise as people who wanted a radical reinterpretation (for some reason?). Especially when there are a ton of big budget action RPG's out this generation, but no Turn Based game even close to the scale that FF7 was back in its day.
