I often curse our luck that the Japanese get all the cool box-sets, figurines and other goodies. But Aksys restores the balance (a little) with a new pre-order limited edition for the American release of Muramasa Rebirth that comes with a pouch, front and rear skins and a lithograph. There's also a soundtrack if your pre-order at Amazon US.
Hopefully Europe will get a similar offer, but we'll have to wait and see. The game is out on June 25, more details here.
