Wow Zeal, that's some analogy! It's all very well thought out and clicks together fine...but i still have to disagree with you lol. Simply on the fact that i don't think KH's goes that deep. It's very much an all round game for the whole family to enjoy.
I just couldn't see the "Waking up and it was all a dream" ending coming to be. Square-Enix are very intelligent and deep story writers, they can see how cliche it would be, even with a fantastically deep, well thought out reasoning as your theory!
But as i said it's a fantastic lot of thought you put into it! Exceptional even!
I'm most looking forward to the story to be honest. Especially the moving moments! *Wipes away a tear remembering Hollow Bastion
