FFX is a great game in my opinion. If you can endure passed Tidus's awkward laughing scene the rest of it is golden and I found it to be one of the best FF stories ever told. I know somke people diss X-2 but I enjoyed it simply because it allowed gamers to get a "true happy ending" (Though it's difficult to get) and it was a nice return to the job system. (With sexy eye candy to boot with all the dress spheres)
PS: Only other thing I could not stand was the blitz ball nonsense. At least much of that was optional. lol.
