Sony Computer Entertainment Japan and Famitsu are putting together a special edition of Gravity Daze. The Famitsu DX pack includes the PlayStation Vita game, 32 page fan book, and this "Gravity Kitten" t-shirt.
Kitten, Kat, get it? Kat is the protagonist in Gravity Daze, if you missed that. This bundle costs 7,980 yen ($106), a game with the fan book as a preorder bonus goes for 5,980 yen ($77).
Compare that to $39.99, the price for a retail copy of Gravity Rush in North America.
