this is a tough one because i enjoyed the vast majority of them but if i had to pick it would be halloweentown because it brought back a lot of memories of the movie which was probably my favorite growing up. what about yours? which world or worlds did you like the most from kingdom hearts?
Easy, Timeless River, really reminded me of Walt's classic works.
They were all great but Halloween is my favorite holiday so I'd probably have to agree with you. Simba's level (Deep Jungle?) was good too. Aerial's was a little frustrating at first.
Mine would have to be Hollow Bastion, mainly in KH1. Radiant Garden would also be one from Birth by Sleep though I felt there could have been more to it, despite how big it was anyway.
Deep Jungle. It just is.
Although, if you mean in general, my favorite would have to be "The End Of The World", or the original Hollow Bastion, both of which are extremely nostalgic. Pride Land from Kingdom Hearts 2 is also worth mentioning.
However, the one with the most storyline, Castle Oblivion, would take the lead as the most important. In my opinion. Which is totally professional.... even though I probably spelled that wrong.
