So I've been offered to get a copy of this game for NZ$20 (roughly US$10), and I'm not sure if I should take it. I've got FFIV on PS in the PAL anthology (IV and V), and a save file with the game complete and characters around level 60-70 (I think; it's been awhile).

I know the new version has some major changes (though not as major as the GBA version, which I never played), but are they any good? And what are they (the additions/subtractions) anyway?

Basically I just want to know if there's much point getting this game when I have the (sort of) original version. What are it's strengths and drawbacks?
