so i was fighting yu yevon yesterday and about to beat the game for the first time, when yu yevon used ultima and did 9999 to every member of my party. i was really pissed, but then everyone came back to life, and i noticed that they all had auto-life on them. i talked to my brother about this (he has also beat FFX) and he says that auto-life is always on after beating Braska's Final Aeon. he said he alwasy thought it was a gift from the fayth or somehting, so you wouldnt lose the final fight. does anyone have any idea of why you cant lose the final fight to yu yevon? im just curious, because its weird that they made the game end like that.
