Great review! Maybe a few things I'd say about it.

1. Characters - One of my favorite casts, very well designed. I also like most of the interaction the characters have with one another, and the love story between Zidane and Dagger is one of the more realistic and thoughtful relationships in the FF series.

2. Story - One of the highlights of this game.

3. Kuja - This is how villains should be. Not completely evil (Exdeath, Kefka), but still having their own reasons why they're against the protagonists. Oh, and I do hear too much complaints about Rikku being half-naked in FFX-2, and I find that stupid too, considering there's more to her character than looking like Christina Aguilera.

4. Necron - A tribute to Chaos, Dark Cloud, Zeromus and Neo-Exdeath, I'd say. I don't think the crystal was destroyed, though, since I thought all life would instantly come to an end if it was destroyed, and Necron came to end all the worlds because he thought people had lost their will to live because they tried to destroy the crystal, the source of all life. Besides, you'll see the crystal sparkling at the very end of the game, during the ending credits.

5. Music - I could go on about this for ages, as FFIX has my favorite soundtrack. There's about a 150 songs in the game, and over 30 of them have been fully orchestrated for the cinematic scenes. That is one huge soundtrack! And I find only one song out of them all to be annoying, and that's the one which plays during the ceremony when Zidane/Dagger and Vivi/Quna get "married". I don't like that high-pitched sound. I noticed a clear step up in synth quality compared to FFVIII's OST, and the game's main theme, Melodies of Life, is even more emotional and better used than the Eyes on Me theme in FFVIII. A lot of different styles too, it's mostly a bit like baroque, and somewhat like the music from the romantic era. Great for a fantasy setting. In addition to those styles and orchestral music, there's still some rocking and upbeat songs too. Great work by Nobuo Uematsu.

6. Graphics - One of PSX's best. And the cinematic style FMVs are breathtaking.

7. Difficulty - Not too hard, although I think it's still harder than FFs VI, VII and VIII. The toughest parts are on Disc 3.

8. Minigames - They're pretty fun. Chocobo Hot & Cold is very addictive and a really fun minigame to play. The duel between Zidane and Blank is also great. The card game has the disadvantage that it's pretty much useless after the card tournament at the beginning of Disc 3 since you can't turn cards into any items that can help you in the game.

9. Conclusion - I could quote Kawaii Ryűkishi, but Christmas already did it (it's in my signature anyway), so I'll quote Crossblades, with a bit of editing since there's one part where I don't think the same: Indeed, FFIX is a great game. It ranks up there in my list of favorite FFs, along with FFVII and FFIV.
