Out of all the game's I'd probably be more likely to say 'yes' to a remake of this one compared to others, but I'm not.
I really don't think there'd be enough substance to a remake game or spin-off for FFIX.
The only real curiosity that strikes me at the end of the game is the fate of Kuja in the ruins of the Iifa Tree. While it is left open-ended, I'd like to have a final answer, but I have a feeling it would probably be horrible and piss me off that they ever made a sequel.
