Final Fantasy X had an extraordinarily compelling story to it. It had many emotional moments and the ending was spectacular. Final Fantasy X-2 also had a really good story, hidden behind many elements that a lot of gamers can't/refuse to see past. The story of FFX-2 is just as compelling as FFX's story, in different places and different ways. FFX-2 did nothing to ruin the story of FFX, they are two very seperate stories.
