So why isn't it?
looking at it briefly, i have no idea. nothing strikes me as odd after a search and a look at the game's wikipedia article. that being said the Goozex listing has incorrect box art so this may be a database issue from rovi.
Trading info says
Trading instructions:There are conflicting End User Agreements regarding the trading of MMOs that prevent the full transfer of title between users. Therefore Goozex does not allow members to trade these types of games.
But I don't see how this would effect this game. I asked this months back and no one gave me an answer. And it's the only DBZ game I don't have for ps2. Go figure.
