the first time i played it i only put in about 8 hours and hated it, now that I've put in over 140 hours (between the original and the Japanese only Zodiac version) I really enjoy it. I prefer playing my Zodiac version because its easier to tune out Vaan and Penelo's voices. Plus any problems I had with the combat got ironed out.
I hate Vaan mostly because he was there to sell games. All of his origin story and setup could have been used on Balthier or Basch who were a million times more interesting. Aside from Vaan and Penelo no one else gets their backstory explored just hinted at.
FF X and XII are the games where S-E made the game then wrote a story to it, and it shows.
I felt kinda ripped off as an Ivalice fan that there were no playable moogles, Kiltias, nomouhs or baanga.
Also Gabranth is in Dissida and he fits pretty well especially with the first 6 protagonists most of which are in heavy medieval gear, who really doesn't fit is Tidus in his freaking jumpsuit.
