Valley Games started out as two friends looking for what they could do for the gaming community. They decided to start publishing new quality games and reprint beloved classics. Their first game was Die Macher. In order to be able to run kickstarter campaigns, these same people later set up Radiant Gaming as a US company.
After various legal troubles, undelivered Kickstarter projects, the expiration of their website, and the emigration of one of its principals, Valley Games effectively no longer exists. (There are various relevant forum threads, for those unfamiliar with the situation.)
