Square Enix has announced a brand-new version of Final Fantasy VII for Steam. This is not a patch. It’s a replacement.
The existing release will be renamed FINAL FANTASY VII 2013 Edition, while a new version becomes the default Steam listing. Existing owners get both versions for free but save files will NOT be compatible between them.


it seems likely, FF7 is one of the most voted for games on their dreamlist and 4 FF games released on GOG recently
Yeah, I was surprised that FF7 was not included, but 8 and 9 are. This re-release could be part of reworking whatever is needed to release on GOG. Also 6 is missing for some unknown reason.
