Regarding your last statement - it's interesting. I actually really liked the game but felt there was no reason for me to play it again, it just doesn't have replay factor... especially since I got all the trophies, so I have no reason to go back for that, either. But now that I've played FFXIII-2 I can't help but want to play again.

...I probably won't anyway, I'm too busy with FFVI and I still have FFIX to beat, too, but yeah. If they do make an FFXIII-3 someday, I'll probably get that and then want to play FFXIII again. And if I don't have any other games to play at that point, then maybe I will.

EDIT: As for music, Snow's Theme was easily my favourite. I loved it every time it came on, and perhaps it's mostly down to how noticeable the music was compared to other background music that would play at various times. Still doesn't compare to Crazy Chocobo in FFXIII-2, though.
