I can't. I have to divide this into sub-categories.
Disney
- I absolutely love Deep Jungle. Like Launchpad McQuack said, coming off the heels of Wonderland and Olympus Colosseum, Deep Jungle feels very organic. I definitely love the atmosphere, the ally, the field and battle music, the whole payoff with the waterfall platforming area after you defeat Clayton. DAT KEYHOLE SCENE. I was always partial to the movie too, so that helps. Atlantica comes next. I loved swimming (and the tact it forced upon players)~ Not used to seeing so much Deep Jungle love. I seem to appreciate the KH1 Disney worlds that are generally liked the least. ;A;
Original
- End of the World. It's so haunting and ethereal. I love all of the random, dazzling, fluorescent locales, the choir that sings the soft and strong arrangements of "Destati", the Chernabog battle, the hints of destroyed worlds left behind, the mysterious words read from the computer in the Hollow Bastion lab, Billy Zane's voice acting Ansem SoD's speech on Destiny Islands, of coarse, the climactic series of final battles, & SO MUCH PURPLE! *u* Hollow Bastion is indeed a close second. It had a creepy majesty to it as well, some great scenes and music.
