Hell they coulda tried to get a license from Anna Kournikova again and had her use a tennis racket, heh that woulda been wierd...
For a minute there, I thought you said Anna Nicole Smith. THAT would have been weird.

Anyways, back on topic. I agree that Tidus isn't well-known enough to be in those games. He's only, what, 3 years old. Plus he's much more of a wimp than the people that are in that game. So he doesn't exactly belong.
