I've said it before and I'll say it again, RPGs are all 'bout the story, of course the fighting matters but it shouldn't rule what's special 'bout rpgs, and that's the strong storyline.

I love FFX-2 to death and if you though FFX's ending was too harsh on Yuna and you wanted it all to be resolved then get FFX-2 if you were satisfied with FFX's ending then don't. I personally love it. Here's a review from IGN which is better than anything these amateurs would tell you.
