Well, I can't really say for sure, but I remember seeing :CoM at Target in 2004 and remembered some vague conversation about 2 years before with a couple of friends in the schoolyard- "Yeah and the first boss is your shadow, it comes out of the ground and you have to fight it on this big stained glass thing" was about all I remembered, but I also remembered seeing a commercial and liking the song, so I got it. And then I got KH1, because I liked :CoM. And the rest is history. xD
