First, some concessions:
- Square Enix owns the title and every game within it, other people just work on it.
- There is a council of people who have the final say on everything Final Fantasy.
- These two entities can do anything they damn well please.
That being said, my
personal opinion: something about giving writers and directors an isolated world and then modifying its scenario and world lore without them, sometimes over a decade later, feels wrong.
Say the company puts Hironobu Sakaguchi in charge of an isolated Final Fantasy V around 1992, and he says "This is Omega! It just came through the Rift! It's a mystery!"
If someone is put in charge of an isolated Final Fantasy XX in 2050 and says, "This is Omega! It just came through the Rift! It's the same one from Final Fantasy V! It did ... you know, whatever it did to get to that game, and came to my game!" that's one thing.
But isn't it something else for someone to say, "Actually, Gooch-san, it's not a mystery anymore. Your Omega now came from my game."
It's fun for
players from the crossover point of view, and it makes money, but it also says that it's okay to just take it for granted that the structural integrity of any game is up for grabs.
At least
Return to Ivalice, if it actually connects the two titles, is overseen by both Naoki Yoshida and Yasumi Matsuno (Final Fantasy Tactics director and writer; Final Fantasy XII concept creator and scenario writer).
The problem with trying to keep it all straight as a fan is that even though SE never fully crosses that line (as far as I can tell, I could be very wrong here), they keep throwing rocks at the hornet's nest knowing people might see it for more than an homage, nod, semi-canon pseudocanon-postscript-superboss, fun event, etc.
For me, Dissidia is the
Alien vs. Predator of Final Fantasy; a sort of alternate universe whereby there are new crossover rules in play. But do these things go backwards, too? Is Dissidia now canon to Final Fantasy X? Is that just where Tidus and Jecht went now? Should it come up in X-3? Should Wakka talk about his time in Kingdom Hearts? Why doesn't Y'shtola ever mention Cosmos?
"But Gilgamesh clearly said
Bartz" echoes through my head again.
Do we then shun FFIX for not getting on board with Gilgamesh? If they're all the same, does Type-0 Gilgamesh now concretely define him as a l'Cie in games where Fal'cie and Bhunivelze and Etro aren't things? Is Shinryu now concretely an aetheric thoughtform in every game? It was Ilberd and the Allagans all along? Is it enough for Final Fantasy XIV to be the origin of Omega and Shinryu ... in Final Fantasy XIV?
I just flee screaming from all of these and follow the Opt-In Doctrine, lol.
