Final Fantasy 4 is my favorite, Final Fantasy 7 my least favorite. I'm not sure about the relative rankings of 1, 5, and 6 yet, particularly since I haven't yet finished 5. Some might be ties, anyway. I think it's sort of hard to take a bunch of games that I liked, perhaps liked nearly equally, and put them in a list that says I definitely liked this one more than that one. ~IF~ I'd rank games on a scale from 1-10, I'd give good games lower scores here on average than if, say, I reviewed them for EGM.
I LOOOOOOVE Flying Omelette!
