Update:

You might want to pour some cold water on yourself. Game Freak's collaboration has been revealed - are you ready for... Soliti Horse?

Horses and cards!

Siliconera reports Soliti will be available next week on the Japanese 3DS eShop, which is effectively a mix of solitaire and horse racing. Players switch between races and card-playing, which... somehow affects horse statistics and abilities. This will be Game Freak's first self-published game. Perhaps not surprisingly, there's absolutely no indication of this leaving Japan... but maybe that's okay.Game Freak, the developer that has worked primarily on Pokemon for the past twenty years or so, is teasing a new "collaboration" on its website The text reads "A classic game that's played all over the world will be reborn in a surprising collaboration". It's partially obscured by a bloom-heavy silhouette of... a four-legged armoured Moomin? A Pokemon that I don't recognise? Who knows.Game Freak has made HarmoKnight and 2005's Drill Dozer as well as all the main-series Pokemon games, and also made the charmingly bizarre Game Boy Camera software for Nintendo's Game Boy Color. Surely this must be Pokemon-related, but perhaps not. What do you think?
