See, Nexus, I'm a HUGE fan of Treasure Planet. Yeah it might not have been up to par with frickin Frozen, but I loved that movie so much! I think it'd be an awesome world just like Deep Space was 
I heartily disliked Frozen but I can't think of too many other worlds with a snowy theme other than the mountains from Mulan which we've already seen, so if they could handle it well without annoying me too much like the movie did, fine. But yes, yes, and more yes on the Treasure Planet. They need an outer spacey world sci-fi thing that isn't Tron or just the journeys between worlds in the gummi ship.
And Zekro, bro, if you read what I said, all I was saying was be literal, and if you have a dissenting opinion, don't be shy about giving your reasoning. It's one thing to think one side of an argument is unreasonable, it's another thing altogether to understand why it's unreasonable or just why someone might think so. I don't care if you loved FF6, that's totally fine. On the other hand if you hate it, I get that too. I just had no idea which thing you were getting at because of a questionable emoticon choice. Hence why I seldom use them. The game does get lots of hype that I don't feel it deserves, so the less we see of it in KH, the happier I will generally feel.
Frankly, that reminds me; Espers from FF6 were such a huge part of it and they actually talked and interacted with the characters, so wouldn't it be cool to see certain summon monsters that are so iconic to the series as part of the KH cast, just like the human(ish) Final Fantasy characters (since they also have Moogles and such)? They could be sage-like, testing Sora in combat like mystic beings and maybe upgrade his magic for him if he passes their tests. Ramuh for one comes readily to mind as that big-bearded old dude who would undoubtedly have lots of lessons to teach the young hero.
