Why is everyone quoting that 5/6 year old post?
FFVIII was a really good game but probably the weakest one from IV - X and had a lot of 'hiccups'.
Personally i think FFVII is overrated (though still a great game), it has multiple bugs and errors in the gameplay as well as an obvious end.
The so-called "unbeatable" weapons are cheesecake with the proper preparations and practically everything can be beaten as soon as you get Cait Sith. As someone else stated, FFVI is better in almost every way, even when it comes to story.
Final Fantasy IX is fantastic
It let's you get to know each character, it actually has a superboss whom even being fully prepared against doesn't make you unkillable, the chocographs gives it a great adventure/treasure seeking feel, the story is good and the music is awesome. It does however lack any kind advanced character development and Tetra Master is such a bad game compared to Triple Triad on the Final Fantasy VIII.
Final Fantasy X was another great game, but Tidus was pretty much a pussy.
You can call Cloud and Squall the big emo-boys but at least they had some guts in the end.
The sparegrid system introduced some paths for character development (though everyone eventually ended up with the same) and was a fun twist.
Blitzball was brilliant on everything from Ramstein - Otherworld to the actual game and how they included it in the story.
The Arena, the Dark Aeons and Penance gave the game a certain difficulty at end-game but the fact that Yojimbo's Zanmato was possible to use almost all the time made it all easy for those who got stuck and still wanted to brag about beating the mentioned challenges.
I simply cannot get myself to rank FFVII or FFX over FFVIII, but Final Fantasy VI was a masterpiece and apart from Tetra Master and the lack of any advanced character development on FFIX it was right up there with FFVI.
Of those i would have ranked them like this:
1. Final Fantasy VI
2. Final Fantasy IX
3. Final Fantasy VIII
4. Final Fantasy VII
5. Final Fantasy X
