I've played all the games but I have to say Birth by Sleep is my favorite =D
I loooove love love Aqua!
She's my favorite character from Kingdom Hearts! She's just so perfect
I love the KH fighting style, the command style from BBS is my fav though.I can't wait for KH3 (though Nomura said it wouldn't be out till after 2012...)It's just such a great story (confusing though O__o) but I love it^_^
