I'm assuming you've played all three but just haven't finished 9? I'd go with that one. FF7 is my favorite of all time but I did enjoy 9 as well. I didn't mind 8 but I just didn't like the battle system.
I haven't finished 8 either. Damn you, Ultimecia!
It ain't quick if you decide to fight Ultima Weapon.That's easily a 45 minute fight just by itself,from what I remember.finish it man, its a quick game.
In VIII you can eventually kill anything in a few minutes with the right limit breaks. Still good though I think. The first one I played and pretty much went through it twice.
Finished IX a couple of months ago after not getting around to it years ago, a lot of fun. Perfect game wise you would have to do 'impressing all the nobles', the jump rope challenge and speed run to excalibur 2 though. Could be a lot of grief.
Been having more trouble getting into VII, still about 15-20 hours in after buying off psn at the same time as IX.
