Long story short, Nordic Games and Frictional Games couldn't reach an agreement regarding the prices of these games so they're pulling them from the store. They may return, but nobody knows when. So if you wanted one of these you better get it now. Many of these are already on Steam and this probably won't affect you one bit, but there are a few exclusive games like Silver that you might want to grab if you don't already own it...
