Wow, I must say you come to some very important conclucions with all of these arguments. Very interesting reading material indeed.

I remember when I first played Final Fantasy X I didn't like Tidus as much as I liked Cloud or even Squall, but I just thought that he was OK. To me the story of Yuna was much more interesting and tragic, but naturally as time went by and I was getting closer to the end of the game I really started to like his character. Like you said, he grows a whole lot and his noble-ness towards the end literally caught me off guard while being heart breaking at the same time. Tidus is truly a great character and his development throughout the story is nothing less than remarkable. Square really knows how to make amazing characters... they really do.
