I'm gonna preorder Dragon Ball Xenoverse in the next day or two! Excitement! That's why I temporarily changed my avatar to my favorite DBZ character. He might not be in the game, but who cares?
I like that Battle of the Gods doesn't follow the EXACT SAME FORMULA as every other DBZ movie. The bad guy kicks the good guys' butts, Piccolo rescues Gohan, Goku saves the day. In BotG, Piccolo doesn't save Gohan.
