well, i liked FFXIII just as much as i liked FFVII just as much as i liked FFIV.
i actually haven't played a FF yet where i had a feeling of my hands getting numb of playing a boring RPG.
well, i didn't own FFX-2, but only because i didn't want the cool ending of FFX to get destroyed by a lame sequel (why does every game need a perfect ending anyways, what's so bad with open endings? leaves place for imagination and speculation!)
