If you're a huge Kingdom Hearts fan looking forward to the July 31 release of Kingdom Hearts 3D [Dream Drop Distance], you might not necessarily reserve a copy, but you might want to. Not because it'll be all sold out when you go to buy it, but because you can get some unlockables by pre-ordering it at participating retailers.
Pre-ordering Kingdom Hearts 3D [Dream Drop Distance] will net you three AR cards while supplies last. One card will unlock a 360-degree viewing stand that lets you take a closer look at your Dream Eaters from all angles. Another card will unlock R&R Seal Dream Eater, and a wild AR card will unlock one of three rare Dream Eaters: Ursa Circus, Sudo Neku or Mewjesty. I'd want Mewjesty just for the name alone. Plus, a crown. Crowns are always awesome.
