Well, yeah, I loved Kingdom Hearts, hands down (my opinion) being that it is the best Free roaming RPG out there. I mean I just loved the idea of the First and the second, although there was one downside to the second and that would have been the amazingly long prologue. My fastest time through the whole prologue was still a Gigantic 3 hours.
And so that really put me off for about a month, and then I just went back and played at it continuously and found that the Characters in the Prologue, did in someway have a connection to the official characters. I won't say anything about that, because it could be considered a spoiler to those who haven't finished (or just started) the game.
But anyway, the characters were also cool, and I loved the fact that they made everything tie so beautifully in with the Disney films that many of us here know and love. The whole Final Fantasy was involved in the Disney Films was also cool, and it actually made sense in a kind of strange way.
This was like the perfect combination for me, because I happen to be a huge fan of the Final Fantasy series, and a huge fan of the Disney films. And plus you have an unbreakable bond of Friendship (between the characters who appear to be the main). And that would be Sora, Kairi, and Riku. That was just such a bond of friendship.
