On the subject of aging and how its affected my view of KH, I think the number one thing is that I don't feel embarrassed about cartoon characters being lame. Donald and Goofy have the most emotionally resonant scenes in KH3, and I generally look forward to the silly stuff more than the more lore heavy stuff (which I enjoyed more as a kid and teenager).
That, and... running through an area and hearing the familiar sound of a bunch of heartless spawning in is like time travel for my brain. "oh damn I gotta kill these guys". I hear that shit and I'm a kid again. That and the familiar plonking sfx of the menus. I like being an adult (except for all the damn work I gotta do) but a skill you must learn as an adult is being able to access the childish part of your mind when engaging with things like Kingdom Hearts. If you're sitting there playing a Disney game and thinking "this series hasn't changed enough to reflect my grown up mind", you're the problem, not the game
