That whole cloning thing was a very good idea, although I am the type of person wh'd attempt that shit they did in Wierd Science. Just wanted to say, i think Rikku's the coolest, and she's fucking beutiful! But I do the the one from FFX-2 is kind of a lil' kim imitator, but she weas more clothes. Everything about Rikku is so cheery, goofy, and optimistic. (a lot like me) Although she does act a bit childish at times, the game wouldn't be the same without her.
For anyone who's read Love Hina, by Ken Akamatsu, you can draw a strong relation between Rikku and Kaolla Su. They're both Princesses of a desert island, they're both overly optimistic, they're both utterly hillarious, and they make the comedy of the story what it is.
P.S. I know whoever came up with that cloning Rikku idea was a guy, because a girl would'nt want to go through the trouble.
