I read somewhere else that you are going to stop selling these games, is it true?

yes it is, hurry up if you want some of these games

This is unfortunately true. Due to some contractual/financial disagreements between GOG and the publishers these games will be removed next week. They will hopefully return in the future but this could be in a few months, next year or never.

yes as others have stated it is true. Sadly thanks to GOG's move to allow users to buy games with different currencies it seems that Nordic and Frictional Games have decided to pull their games but not before allowing users a chance to buy them at sales prices(save for Machine for Pigs)before they are pulled. The reason for this is as I said due to GOG's move to allowing different currencies and it seems when GOG sold only in USD the prices were the same as they were in other stores(i.e. say a game is 9.99 USD here it is usually the same price on other stores) but it would typically cost you that amount in your currency despite the game may costing more in your currency on Steam, for example: at current exchange rate 9.99 USD would be around 7.60 Euros. But the issue seems to be now that same game while still costing you the same amount is now noticeably less on GOG and GOG is refusing to allow for them to raise the non USD price to the prices on Steam and other store fronts.

So yeah, this will be your last chance at getting the games as while there is a chance they can come back there like Hostile Waters and a few others, there is still a chance that it wont like Colin Mcrae Rally, 1nsane, Chessmaster, Obscure, XII, Fallout 1,2 and Tactics, Guilty Gear x2:Reloaded, ect.

I know this might sound 1sane, but it's still here.
