I already feel guilty saying this stuff, because the amount of love I have for KH3 makes my complaints almost obsolete, but there are a couple teeny things I wanted in it that we never got.
•First and foremost, I wanted Kairi to DO SOMETHING. *sigh* Where's my spunky, bossy, tomboyish girl from the islands? The Kairi I loved died when the credits for 1 rolled, and I suppose I should just get over it by now.
• I would have loved a few more one-on-one fights with Organization XIII members. Not necessarily at the Keyblade Graveyard, not as a part of the war, I think the group battles were tons of fun for that part of the story. But I wanted a go at Larxene and Xigbar (hehe) and the rest of the gang, all on their own, with a bit more difficulty and nuance.
• I wanted more original worlds. I wanted to go stare at the clock tower in Twilight Town, to wander through Radiant Garden chatting up Xaldin and Aeleus and Ienzo, running little errands for them or whatever. I wanted to wander around the beach at Destiny Islands and see if the seagull eggs were still on top of that palm tree. I WANTED TO EXPLORE SCALA AD CAELUM.
• And lastly I wanted more playable time as Riku, or any of the other characters. C'mon, lemme explore the RoD with Mickey! We got that one little surprise battle where you-know-who was playable, but doing that only made me hopeful that other characters would get even something as minute as a one-off battle, but it sadly was not to be.
