A thought I had earlier today. FFX is the last traditional Final Fantasy game. That game is the last we'll likely ever see of what people consider Final Fantasy. From XI Square really tried to experiment with each new installment. I wonder if this was an attempt to keep the series relevant.
When you get down to it, FFXI in particular is a radical departure from everything the series had established before hand. Given it's nature as an MMO, that means that random encounters and turn based battles were pretty much completely out the window. Say what you will about the FF games and their linearity, but the series up until that point had been based in tight plotting (I mean this in a game play sense, although it usually also applies in narrative terms) in a very controlled envroment. Which is fine, but then XI threw that all out the window. Being an MMO, this kind of had to go. Of course, most people don't know this, since FFXI was an MMO a majority of FF fans didn't play it (hell, today most people either act like it doesn't exist or flat out don't know about it). XI really should have been a spin off.
Anyway, then we got XII, which is a horribly underrated game and doesn't deserve to be as overlooked as it is. XII took a lot from XI, which, again, is something that most people don't realize. I feel like Square had a very MMO-oriented mindset when they designed FFXII. The game also lacks the tight plotting seen in earlier games. Instead, it leads you very loosely by the hand from place to place. Ivalice is huge, and the game encourages you to explore it. Hell, I'd even say that the side content is handled much better than the main story is. Because when you get down to it, outside of the main story, the game has a very MMO-like progression in many ways. Doesn't help that they outright lifted 80% of the game's mechanics from FFXI.
And then we come to FFXIII. Regardless of what your opinion on the game is I'm going to discuss what it is, not its quality. Anyway, after moving away from the feel of previous FF games FFXIII feels like its oddly in limbo. It attempts to bring back the tight plotting (if it works or not is up to you) and intentionally recreates many elements of previous games. However, it simultaneously tries to push away from the series roots and tries a number of new things such as the removal of traditional towns, shops, and NPCs. Not to mention the battle system, which straddled the line between turn based and real time, taking elements of both. Again, the series at this point seems unsure if it wants to move in the bold new direction started with FFXI or if it wants to return to how things were.
Things finally come full circle with FFXIV, which I'm sure is going to be skipped over in future discussions about the series given its status as an MMO. The game celebrates everything FF, making a number of references and directly emulating elements of previous games. Interestingly, the series actually manages to return to tight plotting in the game's main quest. However, given that it's an MMO the game play seen in previous games is once again gone. This time, however, the game moves away from many of the dates aspects of FFXI and replaces them with their modernized variants. That being said, this still isn't quite FF as it was. Not to say that's a bad thing.
Now FFXV is on the horizon and Square seems determined to keep pushing the series in new directions. I'm not sure how I feel about FFXV right now, since every interview I've read about its game play makes it sound like a streamlined Kingdom Hearts (which isn't a good thing, KH was streamlined enough as it is) but I remain optomistic.
Anyway, I'm sure most folks are going to take one look at this and brush it aside as tl;dr but its food for thought.
