Lets see, the character you control for the ENTIRE game(aside from the Via Purificio where you start as Yuna or maybe another place or two Im forgetting) is Tidus. The game starts with Tidus, Auron tells him its his story, Sin brings him to Spira, Sin is his dad, Tidus narrates the entire game, hell he even takes over the Aurochs for Wakka, the romance with Yuna, the fact that without him Spira would have never changed and Yuna would be dead from the final summoning. Why we are even debating this is laughable, Yuna is a best supporting actress to Tidus' lead role.
