The amount of assets, world building. and capital that went into that game forced Square to keep making sequels and reusing existing resources.
So you're saying FFXV trilogy confirmed?
You know, I think I'd actually enjoy an episodic Final Fantasy game (or just a plain ol trilogy). Not something like the FF13 or 7 stuff, but one long story like Mass Effect or The Lord of the Rings. Something designed from the ground up to be a singular massive epic.
