I'm pretty sure they not meant to be either / or. Whether they're industrial-esc like VII, VIII or X (a world that was industrial-esc, but is now in ruin), or Medieval like IX and the early ones, they're still Final Fantasy. XII actually seems to have a mix of medieval and industrial, IMO.

There are loads of other characteristics that make it a final fantasy, like summons, weapons of the same name and type, chocobos, airships, a dude named Cid, etc.
