If you were Tidus, what girl would you have went for?

Rikku is jailbait, Yuna is a spineless follower who would bore me to tears.

Lulu is your only real option.

18 year old guys are childish dumbheads anyway.

Hey, I take offense to that you big dumbo!

Now that I think about it though I do remember my first playthrough of FFX talking with Lulu in Macalania and saying "Actually you're more my type Lulu" and she replying with "huh... Maybe I'll have to put you on my list"

That happens in Guadosalam, and if an invisible stat called compatibility is higher with Rikku than Lulu, you also have the chance to hit on her instead, and she replies with "Maybe someday" in Al Bhed. You can read a FAQ about compatibility and all the things it affects on GameFAQs if you want.

But yeah, basically all the girls have shown some interest in Tidus.
