To expand on my second point. *SPOILERS*
Final Fantasy 4 had an appeal to me in that there was little to no Sci-Fi elements in the 4 universe save a little trip to the moon. It was ALL magic and crystal shenanigans. They throw that out the window here in the last 20 minutes of the game. I feel like the end game writing essentially rewrites everything you've come to know and love about FF4 lore, turning it on its head in the interest of a cop-out-omnipotent-alien-race sci fi plot "twist" that is better forgotten in the interest of salvaging your fond nostalgic recollection of eidolons, mages, sages and knights.
If that came across as a harsh criticism, then I have achieved my aim. I'm outright saying that the end-game SUCKED and DID NOT jive with the FF 4 universe at all.
Another oddity I cannot understand... why the final boss battle was so simple and easy after the brutal difficulty of the last bosses prior. The last 3 to 4 bosses in the final dungeon had my palms sweaty while any difficulty in the final battle is utterly stripped away with the use a simple "slow" spell (yes the final boss was vulnerable to "slow"...)
You mean, outside of the Big Bad's main goal of setting a giant robot free to rampage Godzilla style across the face of the earth. Or the hovercrafts, airships, floating fortresses, human experimentation, and the occasional mad doctor piloting his Frankensteinian Monster like some kind of Ride Armor. Or even the cop-out omnipotent alien race that the Main Character and The Dragon both descended from (making at least one of them the super special chosen one that all JRPG protagonists need to be) and that the Big Bad and that other guy were both a part of. Amiright?
Well, when you put it that way... LoL
But I still hold firm that TaY's ending takes a far more sci fi angle than any of the aforementioned. Airships, machines, the Lunarians and all that jazz were very "Final Fantasy". Maybe if we care to split hairs, I would call it steam-punk esque or industrial-type-fantasy or something.
Whereas the big departure of...
The crystals are in fact data collection devices/tools from another alien planet and race roaming the galaxy to find a new home.
It proves, at least to me, to be a poorly developed "revelation" that drastically changes my perception of pre-existing lore and takes it from the sci-fantasy styling of FF4/FF6 into an unfitting star trek realm of sci-fi that just doesn't fit.
Let me give an example of how this disturbs me. I will do so in code so as not to possibly drop *spoiler hints* as to the nature of things..
Imagine you got to the end of Lunar and found out that Athena was an alien probe, the Dragons were in fact all robots collecting data for her to complete her mission for Ghaleon, whom turns out to actually be the last of a surviving alien race. It might "work" in some sense, but it sure doesn't fit together very neatly.
One more example and I'll rest my case...
The Lord of the Rings. Lets say the hobbits turned out to be engineered Eugenic flunkies who were lab-made reject results of elves and dwarves. Lets take it further to say the rings of power were in fact just pieces of machinery intended to monitor and manipulate middle earths inhabitants and were planted by Sauron who was in fact an alien.
The FF4 TaY development felt strange along those lines to me...
I guess when it comes to fantasy that incorporates sci-fi anything could
be written in and work. However there exists a fine line as to what is acceptable and what is not given the fantasy in question. Ultimately, my bottom line is that FF TaY is a lazily thought up piece of the puzzle that doesn't fit for me. The only appeal was the returning cast which can arguably not even be considered new in any sense.
NOTE: My bias and disdain also stems from the fact that I liked the writing to begin with. I felt they "set the stage" nicely in TaY. In fact, if the end game revelation was fleshed out with more then one boss and a few dialogue boxes, it may not have proved so jarring to me. Execution is just as much at fault as the actual content (maybe even more so) for the major fail in my eyes. There could easily have been 2 or 3 more chapters that made the existing TaY's ending an awesome twist as opposed to a cheap wrap-up.
