Correct me if I'M wrong, but would any of use buy Kingdom Hearts if there wasn't FF characters in it. Because thats what initially got me interested in it in the first place.

Anyway, I love Zack. I like him a lot more than Cloud cause the latter is a bit too much of an emo. But I wish they would shop using the FFVII characters and branch out to the other games abit more. Even if the others are not as popular, they are still very good games.
