There have been some homebrew attempts, one of which I was involved with, but nothing canonical as far as I know.

My feeling for this game are very mixed. On the one hand it's clearly inferior to FFX and will always be compared unfavorably to it's sister game. On the other hand, it has a great battle system and the original ideas were good.

Frankly it should have been a stand alone game but it would never have been made except as a sequel.

I have problems with the uneven music, the plot silliness, the distracting costumes, but those pale in comparison to my biggest problem with this game: the carryover characters from FFX are portrayed in FFX-2 in ways that demean and diminish their characterization.
