I would like to ask you guys who think x character should have been introduced into x game, I should hear your thoughts on the matter, I like that there was an extra boss to take down that I didn't know about from the start, 1 last challenge, like say a victory lap if you will.

With regards to the whole Yu Yevon thing how else would you explain that the previous Final Aeon defeated Sin and in turn become Sin again, it makes perfect sense to me.
