Not really trying to attack anyone here, just wanted to voice this since nowadays there’s this weird misconception that if fans beg and plead and protest enough, these major game producers are actually going to do something about those complaints (i.e. Pokémon Sw/Sh National Dex, Smash DLC fighters, etc.)
Then you probably know that fans won't stop complaining about it, no matter how much times passes. Believe me, because people have been complaining about Kairi getting nothing since CoM and that was, what, 15 years ago?
Everyone who fights for the FF crew from Radiant Garden to be in the KH series all the time always screams that "it's a Disney/Final Fantasy crossover!" But the fact that they only seem to want Leon/Cloud/Yuffie/Tifa/Sephiroth to appear in KH seems to me that they think it's a "Disney/Final Fantasy VII and VIII" crossover.
Nah, it's just we know it's even less likely for FF characters to appear in random Disney worlds now. They're only ever in original worlds or the Coliseum, and not even in the latter in KH3 (and who knows when Olympus' next appearance will be). As for the Radiant Garden crew, VII and VIII aren't even my favorite FFs, it's just that they are the only ones who have any story connection to Sora. There's also the fact that Radiant Garden is liked as a world period; the FF characters + TRON + the Apprentices + Merlin and Scrooge + heavy appearances of Mickey and Maleficent is a pretty amazing combo that you don't seen in any other world in KH, as the Disney characters have become more and more confined and separated. And then there's the chance to finally go back to the castle again on top of that.
Also, if we're going to be completely realistic here--I doubt Treasure Planet will even happen, much less with FF characters there.
A decade later, the position of FF is more untenable than ever before even with their Re:mind appearance. Nomura and/or Yasue just do not get why they should be included, even though their cameo was as in character as they could be for a 120 second scene. I don't think there's any hope at all that SE characters will be featured in KH moving forward, just Nomura's FF inspired OCs.
Yeah, most people are not delusional about this. I have a feeling Nomura did learn after BbS since the TWEWY characters play a similar role to the FF characters in 3D. Unfortunately, Nomura's removal from XV happened between 3D and 3, didn't it? Or was it before 3D? Either way, I think he was determined to keep FF out regardless after that. I mean, they had already made models for the FF characters for KH3, but Nomura decided that, no, they were
not going to use them.
