This is total bullshyt, plenty of modern games have been of even greater scale than it would take to do FF7 proper.That scale of a game being completely updated to modern standards would take far too long to develop
What information implied that there would be no overworld or towns and play like FFXIII?
I'm not defending anything. I'm pointing out that we don't know how the game will be layed out to jump towards conclusions like this.
being episodic makes having a real overworld not likely. And going by their language of 'with each entry providing its own unique experience' it sounds like they are trying to make each a standalone project, which is again adverse to the style of game the last one was. Also the level in the trailer is more akin to the corridor levels of 13 than the large explorable areas of 15

Even the most technical of PS4 and Xbox games haven't been on the scale of what you're dreaming. The only way is if Square is adding in material that's on the size of another 2 games.
