Suggestion: Chocobo Music Selection
I like how in this game, it's not necessarily about the unique individual mounts (though we still have those), it's about tricking out your very own chocobo with different kind of bardings.
So! Why not music?
I believe that we should have the option to select which chocobo theme from throughout the FF we can listen to while riding! This game already has two, but there are so many others with their own unique sound, and we should get to select any of them -- any of them -- to listen to as we ride, as suits our mood.
No remasters, either. I'm talking literally the same tracks we listened to on NES, SNES and onwards.
Also: Spinoff/sequel chocobo themes too. Because XIII-2's "Crazy Chocobo" must grace this game with it's magnificence, right alongside VIII's rocking theme and XI's ukulele chillout, and all the rest.
