Iīll tell you...
FFIX hasnīt got a thing in common with FFVIII. Since Amano didnīt take part on this title, most people didnīt like the character design. But thatīs a small minus. The brighteness effects that were not in FFVIII make spells and special moves to look awesome. The story itself is pretty cool, and the characterīs abilities are excellent. The music rocks too, and it has tons of side quests (not as many as FFVIII, but they are a lot, nevertheless). I think it has a resemblance to FFVI, but thatīs my opinion. Also, as this was the last title for the PS1, and if you have played FF1, you will notice that A LOT of the characters are repeated here. Cool. Who hasnīt ever wished to see the mighty Garland [bigspoiler] blowing up entire towns [/bigspoiler] instead of kidnapping delightful Princesses? Itīs graphics engine looks newer, plus it has thousands of equipments. And, there you go, you can even fight the almighty Ozma, whoīs strength is compared to FFVīs Shynruu and FFVIIIīs Omega Weapon. I strongly recommend it. Totally.
