Yes, it is the saddest KH so far. Spoiler The ending where Xion dies is actually the most dramatic scene since Axel died in KH2... =P
Actually, those who turned heartless as far as I know never came back... right?
Yeah but how do you know he hasn't already planned this and we're missing something?
Apart for the graphics, the character designs, the wonderful music and the amazing gameplay, I play it for the storyline that always keeps expanding and the moments that are for pure joy and nothing more. The cutscenes you can enjoy watching without getting bored and the beautiful views from Twilight Town. xD
