Today in Theatrhythm: Final Fantasy, I decided to take my chances on a set of music with which I was on familiar.
Things were going well. I managed to score an S on the first two songs (EMS and FMS). This got me 300 EXP on one, and 700ish on the second. Upon completion of those two, I went on to do the Battle round. After only scoring an A on this one, I was amazed to see that I got a whopping 2500 EXP! This was enough to level my (fairly low level) party up three times a piece! I have no idea how I got 2500 EXP, so:
How does this game determine just how much EXP you're getting?
