...If you're saying that KH2 was a rip off... which you are...
I will get a shoe, dunk it in mud several times, then cover it in steel then I'll cover it in the most foul smelling dirt I can find and throw it at your head. Then, I will sick my hawt bishie Nobody on you and make him shoot you in the shin.
And, as Willy Wonka says, "GOOD DAY, SIR!" No, Kingdom Hearts 2 is NOT a rip off. Its one of the greatest Playstation 2 games of its time and should be consider a Playstation 3 game. Every world has its plot and each plot is not distracting for the real plot. The real plot has to do with the actual storyline so, if you kindly go into a corner I won't have to beat you.
