Personally I would've liked costumes to be unlocked by titles. Like get a specific title for hard ones or a number to get the same one. I can't fight the CPU it creates bad habits for me because the game always falls for the same combo string.If they didn't have a compiled story mode, I wouldn't mind re-doing the same routine. What they could probably do to remedy the excessive influx of the girl's costumes in 5U's arcade mode is unlock 5 costumes all at once per level to lessen up duties and get rid of other methods.
