I have played FFs VII, VIII, IX, X, and X-2. There are aspects I like about each of them.

FFVII had an amazing storyline, true, but I like Xs storyline the best. X also has the spheregrid, and I love the spheregrid. In my oppinion, it is superior to leveling. FFVII does have some great points though. FFVII has the most shocking storyline of them all, and as far as I know is the only ine to kill off a main character that the player gets to have in the party. FFIX had great music, I love Mellodies of Life to this day, and it is a close second to a thousand words. FFVIII had a touching storyline, good for those who enjoy the romantic type games, which I found suited me just fine. It also had the biggest cast of chars to choose frim, I think. I would have to check that, though. X-2...It had a few weaknesses sure, but it was fun. Now, a great FF with sucky graphics was Final Fantasy Tactics. I still play FFT just to screw around. It is a really fun FF with a plot full of twists.

Overall, I think I like FFX slightly more than FFVII.
