Hei,

I remember GoG was offering a service where you could redeem your steam games here on GoG.

I have a torchlight 2 linked to my steam account. And I hate to play any game trough their awful client. Is there a way I can get the game key working trough GoG.

Thanks.

Here is GOG connect https://www.gog.com/connect but there are no games currently available. We never know beforehand when there will be, but I guess during the winter sale, which I guess starts next week, nor do we know which game(s) will be in there BUT some games we can guess will NOT be there either due to already have been in a connect offer before or because the publishers are against connect.

oh, ok, very mysterious :D Is there a list of games that will definetly NOT be there?

No. There is the FAQ about GOG connect, you can read it if interested. I am not going to repeat it all here. Link to connect at the bottom.
