Which Final Fantasy is most deserving of a sequel? Don't go ahead and say your favorite for the sheer fact of saying your favorite, think about your answer and explain why.

(For this thread, pretend all FFVII sequels were never made)

Personally, I think IX deserves it. The ending was very open and Necron's dying lines made me think the game was intended to have a sequel. There are so many ways they could take the story, and most characters are kinda left hanging at the end, with no explanations for what became of them or anything.
