You know how Scribblenauts Unlimited has been delayed yet again in Europe? Rumor has it, from a trusted inside source, that the game was actually shipped to retailers. Both the 3DS and Wii U versions had bugs/fixes so important that Nintendo asked retailers to yank the game before it was on sale. Those copies are now on their way back to Nintendo.
Man, imagine if you could get your hands on one of those 'defective' copies!
