I didn't think they went far enough to make the story different tbh, it was one of the most disappointing parts of the game. We still went through every Dragon Ball Z battle in chronological order, except this time someone glowed an evil colour and we needed to stop them. I don't know, throw different characters into different storylines, maybe they messed up time by bringing Cell on Namek on something. I still felt like I was just playing the Dragon Ball story again when I was expecting something more fresh. Another thing I hated about the story was the Mira fights, those were the easiest battles in the game, I cake walk over him and then the cutscene acted like I barely survived the encounter. Final boss was cool though.
