I'm seeing a trend with people who like games like X and XIII over games like XII and V.
For a reference, here's a rough ranking for my FF titles:
XII > V > IX > VII > VIII > VI > IV > III > I > II > XIII > X
I'm a big fan of XIV, but I don't see the point of ranking the MMOs with the single player experiences because they offer completely different things.
I still need to do a lot of the side stuff in XV, and say this point I'd throw it right in the middle. I'm very much done with anime trope characters and ridiculous stories, but there is a lot to the game outside of those things, and that's what I'm into.
For me, first and foremost is the gameplay and what the game offers in terms of things to do. I love FFXII. There is a giant open world that offers things such hunts, and the battles are plentiful, rewarding and streamlined. I can put hours into the game (I've finished the Zodiac version at least three times with things like the hunts completed) and be throughly entertained the entire time. On the flip side, I could barely tell you what happens in the games story. It isn't important to me. The game was a Game first, the story took a backseat. Beautiful world, though. I also enjoyed the characters. I'm still on the side that believes XII has the best dub of any JRPG, ever.
I absolutely loathed X and XIII, with X being the biggest offender. These games threw you on linear paths and forced terrible stories at you. The gameplay took a back seat in these games. X's idea of a dungeon was pushing pedestals. The combat was a joke (X just having you swap out characters to match the enemies weakness, like some sort of simple puzzle game and XIII having more or less the same thing with the paradigm swapping). There was barely anything outside of the main story.
So, while XV had a pretty awful story, it has more to it. I beat the game in a little under 30 hours with a handful of side quests and hunts done, and i can easily put in double that to clear up the remainder. I'll forget about the story. I mean, there was a segment with monsters near double my level swarming me in packs. I actually want to work up to the point where I can beat them.
So we'll see where XV finalises in my rankings.
