Two save slots?! Da fcuk?! In every Kingdom Hearts game to date (with the exception of the original Chain of Memories) I have created multiple save slots for the sake of playing my favorite levels and fighting my favorite boss battles with the the press of a button via "Load" without playing through the entire bonking game.
Hell, in Birth By Sleep, aside from my first 4 files (my original Terra, Ven, Aqua, and Final Episode) I have save files following the Birth By Sleep timeline by verbatim. Why? So not only can I play the game in chronological order, but so I can swiftly jump into any level or any boss at my own discretion.
Needless to say, I am not pleased to hear this.
