That wasn't really hard. I can actually say it was pretty easy. Vesperia was more long and hard to get. Anyway the game was really good even if it lacks extra content (mini games, cameo battles, more in-game costume...)
I. AM. SO. HAPPY. They kept their SB2 moveset but improved. Too bad it seems that they won't have a story mode... But I still can't wait to play as Kasuga
