Haha, what a joke. That game's been losing value ever since the announcement of the Budokai games, going from $550 one summer to $100. Now it'll be $30 or so, and not worth shit.
So, if anyone still is out there, thinking, "WHOAMG!!!shift+1!111!eleven!! NEW DBZ GAME LOLOL," don't. I bought the import a long time ago, and unless you like to press an attack button, and sit, and wait, for the press to be recognized, then do the right thing and pass on it. Trust me, that ain't "strategy"; it's lazy-ass, sloppy programming.
In short, the game is how everyone else has put it. Someone at Bandai took a collossal binary shit, put it on a disc, and morons have been paying half a thousand dollars for it ever since. Don't be one of those idiots.
