flanner: not sure what gog connect is (if something with steam so i dont use steam anyway) but
OFFICIALLY?
i cant see any official article or note marked with the blue dot, so it can be just temporary disfunction.
.. i suppose, gog would announce significant changes
It was a neat program where you could link your Steam account, and if you have already owned a copy of participating games on Steam, you could claim a free GOG copy. The link to GOG Connect was tucked in the footer until now, and it was inactive for several years. You can see why they just quietly kill it.
