Perhaps I worded it badly. I meant that I am going to play two different games at once, both having their own saves. I am not crazy enough to do it in one game.

EDIT: Or actually I am not sure if you got me and I don't get you Either way I already started both games and I am gonna make my first update later today. I already replayed FFIX normally so many times that I want to do it differently for once (or actually twice).
