personally I would really like to see a sequel ( and it needs to be put on the wii and xbox 360 as well so people don't have to buy another console >.>) in my oppinion things were wrapped up well but not well enough.
what happened to alexandria, burmecia, cleyra, and linblum. all of them were destroyed.
did Vivi die soon after? who was his wife.
what happened to the black mages in the village. did mikoto live a normal life afterwards.
what happened to garland (he talks alot in memoria) do the planets merge? (kuja destroyed alot but I doubt that it would destroy the planet)
did freya ever see fratley again.
did zidane and garnet rule over alexandria.
necrosse swore it wasn't over

I think there is enough for a new game and I would like to see one.

In this order: (spoilers for some)

1. They were rebuilt, put simply

2. Actually the period between Zidane's disappearance at the Iifa Tree and his return, Vivi did in fact die. As for a wife, we really cannot say.

3. Well, the Black Mages and the Gnomes go on with their lives, though it would be a bit awkward as the Mages have souls but incredibly short lifespans, while Gnomes have no soul and are nigh immortal. (Except for Mikoto, who has a soul, and a normal human's lifespan)

4. Word of God says Terra was destroyed. So, unification is indeed false. However, you are right in which though a large portion is destroyed, IMO Terra probably is still around.

5. Yes

6. Yes

7. True, and that maybe the only case a person may argue about in terms of a sequel.

Personally, I know there will be a remake, it's only the matter of when, as for a spinoff and movie, I'm a bit undecided, so I can't really make a decision, unless I here more people's opinions.

I think a remake would be sweet. On next-gen consoles, the world could be improved and enlarged tremendously. Also, I think they should have put more time into abilities/character customization.

Yes to the remake! But no to the rest, the remake would be amazing! Final Fantasy 9 is my favorite FF game so of course I'd love to see Square give it some attention!

This game is unrated so much, I think if square remade it I think a lot more people would give it the credit it deserves!

On the subject of sequels. I think what made Final Fantasy so amazing origionally is that even though each title was the same series with one number up, there were no sequels! You got a different world, different characters, different gameplay, different music and different story every time!!

I'd love to see Final Fantasy IX on the PS3 (heck, I'd buy one just for that game, I really would!) but I felt the Final Fantasy VII spin-offs were an abomination and I'd hate to see my favourite title of the series viced for it's money's worth in the same way.

Squaresoft, not Square Enix.
If it was Square Enix, it'd just be a sequel to Final Fantasy VIII with a horrific real-time battle system and a graphical and artistic style that just makes it look like every other game they've released...

I would love to see any of them though a movie by far the least. One thing I would love is if they made it 50% longer and also made it a harder game. Things like Leveling up or monster bashing for gil was basically unnecessary in this game. They could make it harder just by making it longer with tougher battles that you had to be more well-equipped for. Making something like ability placement key to defeating many battles instead of making every battle not losable like it seems to be. Don't get me wrong I loved the game, but if it wasn't exciting plot was it would have been pretty bad because it was too easy. I really liked a lot of the ideas they used, like the abilities system but mastering it just wasn't essential to winning and it should be.
