How can this be? FFX is very similar to The wizard of Oz! But how? Well look at it this way:
Tidus (dorothy) is on a quest to a magical land where he/she can go home. Dorothy takes the Yellow brick Road while Tidus takes the linear summoner's path. Evuntaully he/she meets a dunce in need of a brain by the name of scarecrow/Wakka, also he/she meets a cowardly lion/or oucast Ronso, a good witch helps out/Yuna and Lulu, a strong tinman/drunk warrior helps out, until they get to oz/zanarkand where the great wirzard/summoner cannot do what they want which is destroy the wicked witch/sin and get what they need but she can do this....
so if looked at closely ffx is based on The Wizard of Oz..
