FF9 is fine just the way it is. I like it that way and it doesn't need a sequel. All is in peace now, Garland's gone, Kuja's gone, evil's gone! What could get wrong? Besides, I agree to some point of people it would ruin it. It's fine just the way it is!

But... it's okay if it has a sequel, depending on the situation, but I doubt it. It's not much popular like FFVII that already has a movie and a few sequels. So yeah...

So IF it does have a sequel with a seemingly good story, great and improved graphics like BlackMagicShrine said, since I totally agree with him, a twisted plot, that would be cool.
