EXACTLY!

There is no way Tidus could lead if he has never been to Spira.The developers made it so that the player and Tidus are connected because they find themselves in a new world.

Yuna is the real leader even though she is meek and timid.

Auron is like her advisor.

Tidus is there to motivate people.
