So, when you make your first character, Xion gives you an item to go back in time, and make different choices.
...I took this to simply be a plot excuse to replay missions & make different choices to see everything...Except I can't find anywhere to replay story missions I already beat, or to re-choose my choices.
So then I realized people are saying things like 'Don't you look familiar?' to my character. Which leads me to believe that the whole of Phantasy Star Online 2 is my character already going back in time. The player just does not realize that. Maybe the player character also does not remember? I don't know.
So I'm curious; am I missing something? Is there a way to replay story missions? Or is the whole Xion thing just a part of the story I have not seen yet? (For the record; I just unlocked Saena as a partner)
