To get the World Champion, the walkthrough says...
"If you build Wakka up in Blitzball games, he'll become a hero. When you've won a lot, go to the little restaurant at Luca and the guy there will give you the World Champion."

How do you build up Wakka in blitzball? Can you even get him to play after the first tournament?

yes, go to the airship and press square [] on him so that you can sign him again... you can also sign diferent people like brother, rin...

I hear at some point you can get cid too! He is supposed to be better than jecht, so ive been told. Can anyone confirm this? if its true how do ya get him...?
