FF12 managed to knock 7 and 10 off my favorites list. I
love the story it tells and the way it tells it, and as a game it's quite fun. Only that there's a little too much of it- I don't have hundreds of hours of free time.
FF7 had a really compelling storyline. I'm still not sure what I really like about it, since it features a rather silly, new-agey sort of plot, but I still really like it anyway. The graphics are terrible, and even had I been introduced to it when it came out, I would have thought so. It belongs to that era of games and rendering capabilities that I don't like.
FF10 had a slightly less interesting story, though it still had its aspects, but as a game it's much better than 7. And FFX-2 is kind of weird, but it attempts some interesting things that I've never seen before in a game, and I've played it actually twice as much as the original in an attempt to get that blasted perfect ending.
FF9- I enjoyed it while I played it, but I won't be replaying it. It just doesn't have that extra something.
FF8- I liked, but I technically haven't finished yet. I think that's a better candidate for a remake than 7, honestly. 7 has a lot of humor resulting from the shabby spritelike graphics and bad translation that just wouldn't do well on a high-powered new system.
