The main story can be difficult if you aren't the appropriate level and don't have certain skills. Unfortunately, spamming supers seems to work wonders in single player and I'd say give a definite edge over non super spam characters. Some parts of the main story were super hard for me while building my character, others not so much. All in all though, if you're a big DBZ fan, you'll probably really like this game. The combat is simple and doesn't really have the combos and such like older DBZ fighting games, but the controls were fine and I had a good time playing the game.
