When I first saw this, my first reaction was: Oh, well, Chain of Memories. I like things with really dark storylines, so I was thinking about Sora slowly losing his memory and everything else that happened in COM....
But then I thought about KH1 and I realized that everything that happened seemed to revolve around the heartless and darkness. You Know~
-The islands being ripped to pieces by Riku. (Well, the portal actually, but he helped!)
-Kairi losing her heart.
-Everybody seemed to be controlled by the heartless.
-Riku was going all evil on everybody~ Then he got possesed.
You know, all the good stuff. XD
So I figured that was my opinion on KH1~
KH2 just wasn't an option for me. Wasn't as challenging to play as the other ones either. >.>
