On the one hand, mistakes like these indicate a level of disinterest. "Oh, who cares what the cover says! No one's going to pay attention," say the phantom production managers in the diehard fan's brain.
Than again, it's fun! I personally love a good wacky game package, though. A certain Resident Evil for Nintendo 3DS will never, ever leave my library thanks to its hilarious spine. Sometimes the flubs aren't even typos. Okami on Wii had star Amaterasu on the cover, but it also had an IGN watermark on it. Capcom didn't even use its own art to make that cover!
Do you dig having these oddities in your library? Take the poll, discuss in the comments.
