I guess I'm a bit on my own with my opinion, but I loved the story of FF X and X-2.
The gameplay of XII was definitely the one I enjoyed most, however.
So my favourite is one of those three, I can't decide :hmm:
FFVII without a doubt, one of the best games ever created, actually thinking of getting a tattoo of the logo of that game in the future(after the triforce of course), just the meteorite tho.
