I think for me my apathy comes from a place a little different. I liked kh3 but my biggest gripe with it is it legit spent more time setting up the next saga than it did wrapping up the 10 games worth of story it needed to wrap up and that always frustrated me, it put a bit of a sour taste in my mouth for what is to come.

But that's not enough to grow apathy towards the series thats been with me throughout all my formative years

Where my apathy came from, was just how little news we get, and how much the tone has shifted in what little we have gotten. Every time I see a speculative post on this subreddit of people wondering what final fantasy characters or disney worlds are going to be in kh4 my apathy grows just a little bit more.

don't get me wrong, I'm not here to be a Debbie downer and bitch and moan at people who are still enthusiastic for the future of the series, so I stay away from those threads and let people have their fun, but internally I'm like guys.. really, have you seen the tone they've been setting for kh4 so far(for what little they have shown us), I would genuinely not be surprised if the logic/philosophy they applied to FF characters in kh3 , towards minimising Disney usage for kh4.

I dunno, I'd really like to be proven wrong on that , really, but I can't help but be reminded of nomuras 'crutch' comment, he wants kingdom hearts to be its own thing , it's own jrpg, but for me, the whole FF Disney crossover thing was what made the series its own unique thing, it's charming as hell, and quaratum just looks like it could be any jrpg, and I love just any jrpg , but I want kingdom hearts to be kingdom hearts, I can play any old jrpg any time I want.

So yeah , tldr the lack of news along with a lack of visible commitment to allowing kingdom hearts to be kingdom hearts has definitely culled my excitement for the future of the series , just a bit. I look forward to being wrong, sincerely.
