Best(s): 1 and 8.
1, the only one that doesn't bore me out to play over and over again. Perhaps cuz its the only one that actually gives you the freedom to pick your party...
8, best story of any game, console or pc, period. Simplistic gameplay aside, the story alone (cept the horrid ending) makes up for all other mishaps.
Worsts: 5, 9, and 10
5, well, I liked the idea behind the class/skill system later used (better) in FFTactics, but it just didn't work for a rpg. Add to that a sloppy plot and you have a fairly crappy game in my eyes.
9, bah! Someone out there was smokin crack in the making of 9. Super-Deformed 3d characters do not belong in this world! They said this was the game to be "like the old ones", but i never saw that. Felt like a combination of 6,7, and 8 to me. Not what i call goin back to their roots

But none of that is a good excuse to call this game bad. No no, i'll leave that to the supremely fruity story and UBER simple-minded gameplay rivaling that of FF: Mystic Quest (a game that was suppose to be designed for kids).
10, i actually loved this for about 10 hours of the game. But then it all came to me, this game does nothing but repeat itself over and over. And lo' and behold, after finally beating it, that was all so very true. I haven't touched the game since. I don't even know what i loved about it for them 10 hours :/
a special kudos to FF7... i thought it was a barely above-mediocre game guilty of being nothin but a shiny object in my view (ala introducing fancy-pants movies, long-winded spells, side-tracking mini-games galore, and overly cheesy soap-opera-like moments), but it managed to singlehandedly bring rpg's to the mainstream and revitalize the genre. Certainly helped us old timer rpg'ers by finally gettin the games flowing in.
All the other FF games, i liked, nothin special

And there's my semi-review of the main Final Fantasy games

Like it or not.
