The game "Soul Calibur V"(Not a debate whether XBOX 360 or PS3 is better)

[Vectra]

For all of you who didn't read the full title this is not a debate whether XBOX 360 or PS3 is better. Anyways, Soul Calibur V is a good game no doubt about it. But, the story is way too short. I beat it the day after I got it. I have already traded it in game stop. I'm thinking about buying that game again. But before I do, do anyone know anything else that you can do other than the story, or the arcade(Meaning I want something harder than Edge master difficulty(I mastered all difficulties in the game(Because I play and create games for a living)))
