Replaying X for the first time in at least...gotta be 10 yrs? I have a lot to say actually, seems like this thread is more about game mechanics/quests/etc than plot discussion...but anyway, an aside:
I never noticed this before, and I must find out what the name of the song is, but...it plays as you are preparing to leave Besaid with Yuna, she is convinced to leave behind her 'luggage'. The main melody, is like an almost direct interpretation/variation of Aeris' Theme, only a different key...found it very interesting
