There's no better way to flaunt your mastery of the art of having $55 than with theKingdom Hearts 3D "Mark of Mastery" edition. The newly announced special edition comes with a clear 3DS case and a set of art cards that look like they can be slipped into said case, and five AR cards to unlock in-game Dream Eaters. All of this comes in a big box with a magnetic clasp.
This edition shows one of the advantages of portable games: the limited edition boxes don't cost quite as much as those for console games.
