I've completely not read this thread because I know all it consists of is "Tidus sucks, he's a crybaby and acts like a girl."
Okay okay sure. But put yourself in his shoes. If you were shipped off to another planet, not knowing anyone, about anything, and suddenly trying to save a world that you don't even belong in.. you wouldn't be so calm. You'd be crying too.
Anyway Tidus wasn't that great of a hero in the beginning, but throughout the game his character develops and he grows on you in leaps and bounds. That's what happened with me. At the beginning, I was like, Tidus is just another character to me, but by the end I grew to really like his character.
Just cause the voice acting was somewhat crappy in this game, it's better than not having anything at all. They did improve with X-2, so that's good.
