Apparently Ubisoft made the conscious decision that they could only give away Michael Jackson: The Experience, currently with a sub-66 score on Metacritic across the board - most critics agreeing that it's not really up to much with unusual design decisions meaning that your ability to dance like Jackson is somewhat limited. With reports that the Vita version is pretty terrible, perhaps it's not surprising that an error in the system has made this game entirely free.
Expect the mistake to be fixed fairly soon (or perhaps even by the time this post goes live), but if you download the demo of Michael Jackson: The Experience, you'll also get access to the unlock code as well. Not entirely bad for free, but I wouldn't expect too much regardless. If people weren't enjoying a game in which you can sing and dance like Jackson, they're unlikely to be too impressed by nothing more than an exercise in screen rubbing.
