Why was KH3 used to set up the next saga? I mean KH2 wasn't used this way, and I mean regular KH2 and not final mix. The note doesn't count, yes it was an open-ended ending (not sure if I'm using that term right) but it was a somewhat happy ending, it just feels like kh3 could have done the same thing, have a happy ending while also setting up a future game or games with the same after credits scene (as much as I really don't like relying on the phone games) with luxu and the foretellers. as much as I enjoy the game KH3 just feels like a crutch for the next saga. what are your thoughts? and when I say happy ending I mean no one dying.
I really don't think this is as much of an issue as people keep making it out to be. Sure, the break between sagas wasn't as clean this time around, but I don't necessarily see how that's a problem. There are definitely parts of KH3 where I think the setup for the next saga is too overt and obnoxious, but my issues there have to do more with execution than with the setup itself (for example, I think the way they worked Subject X into conversations between Lea and Isa was terribly obvious and not handled well at all).
I think people don't take into account the opposite problem, which is that if Nomura hadn't made it clear that the series was continuing, then many people might not have understood that KH3 wasn't the finale of the series. There were plenty of people even up to the release of the game that were still under the erroneous impression that it would be the end of the series. Perhaps, given the increased financial stakes of needing this game to both do well and also open up a new broader fanbase to future content, Nomura felt he needed to make absolutely certain that people understood this wasn't the end by a long shot.
Personally, I think all the UX callbacks were more of an issue than setting up the next saga. I can only imagine what it would have been like to go into KH3 not having experienced the UX lore dumps that it ended up relying so heavily on. I think the decision to make a mobile game that few people would have played so integral to the plot of that game was the biggest mistake Nomura has ever made with this series. But just setting up the next saga is not something I have an issue with.
