So far the biggest issue with the game is how god awful the Tangled world was. It was literally just the movie. Most of the scenes in the world were literally just the same exact scenes from the movie, with the same exact dialogue. I haven't done the Frozen world yet, but I've heard that it is also the case for that world. There's very little "Kingdom Hearts" added into the worlds, and it's just going through the scenes of the movies with a few battles against Nobodies/Heartless along the way.

It just proves that they only put these two worlds in the game because they thought they'd get sales for the game doing so, and not because they actually fit into the theme of Kingdom Hearts. Very disappointing to see and takes a lot away from the game. They should have put in worlds that would have actually been fun and could have fit into the theme of KH, like Brave and Star Wars (I mean, come on. KH is about Light vs Dark and Star Wars has the dark side of the force. They could have easily slotted the Heartless into a Star Wars world and made it cohesive).

The only good world so far was Olympus, which was the first world. Toy Box (Toy Story obv) was decent, though it could have been a little better.

One of the most unforgivable acts this game does is the fact that there are no, zero, none, nadda -- not a single Final Fantasy character in this game other than them references Cloud and Auron at the beginning of Olympus. There are other FF references in the game, but for a series that was all about the Final Fantasy x Disney crossover, not having a single FF character is just not okay.

With how the Tangled and Frozen worlds are just the scenes from the movies (complete with the annoying songs in Frozen's case), and the fact that there is hardly any FF representation at all in the game, it almost feels like Disney got their panties in a twist that the series was becoming more of its own thing (aside from the worlds and character appearances, the Disney aspect of KH hasn't been that prominent since the first Kingdom Hearts. Every game after that, the Disney aspect was more of a "hey, here it is" thing. But KH3 feels like Disney told Nomura that they needed to put more focus on Disney than anything, because most of the worlds focus more on the Disney characters and shit than they do Sora and company, who are supposed to be the focus of the game. KH3 was supposed to be about Sora and his allies gearing up to take down Xehanort and his 13 darknesses. Instead it felt more like hey let's watch a bunch of Disney movies... oh yeah, we better give you guys that final battle against Xehanort before we forget.

I think it would have been hard to implement any FF characters into the story of KH3 without it feeling like straight out fan service, considering how many KH entries there are already. I've not played the games so maybe there is a way it could have worked, but as an outsider looking in I wouldn't be surprised if having them in this game had no good way of incorporating them.
