Isn't it obvious? Disney had more oversight over KH3 and FF is too hardcore for Disney.

Disney has no control over how Square Enix handles their own properties in this series

Actually I think it was mostly nomuras decision. He even said awhile back that he wouldnt even make kh3 a possibility if toy story didnt make it to the game. This indicates that he seems mostly a fan of disney than even final fantasy. He also said the he wants kingdom hearts to be more of its own thing by not adding final fantasy characters....despite 3 having been very disney...smh...
How in the world did they think making the game 90% disney, not having more original worlds/levels, no sephiroth battle, no final fantasy characters, make the gameplay lose its touch, etc etc etc, was a fantastic idea??? This is just like vsXii all over again.
Tbh im losing faith in him and especially square all together. Square has been making mostly mediocre console games and putting more of their focus onto mobile. Kh3 lost so many of its core values that I considered very important for any mainline kh game. Having taking years upon years to work on ff vsxiii was misstep # 1, making kh3 a horrible game compared to 1&2 is misstep #2....and my final hope is the ff7remake, if he screws that up....then that is strike 3 for me. I think im done being a huge fan of kingdom hearts, no way can that bitter taste in my mouth will ever disappear.
I want to complain more about the problems kh3 had but that'd take me hours and a massive amount of text lol.

The story got to big for them, they should have just kept it simple and clean (¬‿¬)

It’s an odd decision for them not to have the collesuem back for the final episode in this chapter. They could have easily squeezed in the ff characters there for the fan service

I don’t know maybe I’ll rethink it next time when they start the new chapters and try and keep it down to a trilogy

Every world in this game was small, boring and uninspired. Yeah there was a lot of them but you spend 2-3 hours in each then you have no reason to ever go back there. I would have preferred less but better fleshed out worlds that gave me a reason to care about being there and to have reasons to come back.

At least the FF characters were actually doing something to try and curtail the opening of Kingdom Hearts, or doing something to directly help their worlds. The disney worlds were just being affected by it, and it was Sora who came in to help them, and fix their heartless problems, which they remained clueless on. The FF characters were aware of what was going on. KH often made it a point to say how they couldn't let those in the Disney world know about other worlds.

They didn't need to have a FF world....although that would have been cool...but some characters could have easily been worked in. But there was almost no story in Traverse Town, which is where we usually saw them outside the coliseum.

So all the FF Characters in Radiant Garden/Hollow Bastion just vanished into thin air? Man, that sucked. Square Enix doesn't realise just how cool it was seeing all these FF Characters we grew up playing with in a modern game, and took that away from us.

They aren't random though, and I think that's part of the problem. All those anime characters were all in previous games and had plenty of screen time for character development. They were just under used and their importance was down played

They weren't random characters. They were former members of Organization XIII, or their replicas mostly. Understanding their motives and reasons for being there is where the convolution comes in. If you hadn't skipped the cutscenes, they often went into back story detail....which I found made them boring, because they spent too much time on explaining what was happened before, instead of concluding the story with stuff actually going on. Then they just crammed every meaningful story point into the last couple worlds. Some of the significance of the big reveal would easily be lost if you missed one of the games...not that it was really that interesting, and was kind of anti-climatic.

And that's kind of the problem with KH in general. The main story from KH1->2 had so much side story which was only sometimes important to the Xehanort connection. The only one that really mattered overall was the one that introduced Roxas, and Namine, and they were disgracefully underused, or completely absent.

Saying you skipped scenes and missed nothing in the same sentence is really funny. Because you did miss things, a lot of things apparently. I wonder why you think the story is so 'convoluted'? Maybe because you didn't actually pay attention to it. There's a lot going on, but it's not really that hard to actually follow.

Well the games creator Gary Newman confirmed it himself on Twitter.
