Loved hollow bastion/TWTNW alot of story there but if I had to pick my favorite based on worlds... Space Paranoids, I mean I never expected to see Tron... NEVER and man I was a blue guy... it was just too much fun.
Atlantica I liked too not enough to be a favorite but atlantica sucked in KH1 the swimming was just far to annoying... I'm sure they coulda fixed the control issues but my favorite thing about The Little Mermaid and the reason its probably my favorite disney movie.... Aladdin being a CLOSE and I mean close 2nd.. is the music... and thats what won me over it was a nice change of pace and no where near as boring as doing 100 acre wood.
