I hope we can have GOG Connect in this promo.
I'm afraid GOG Connect is dead :(
You can blame Platform Integrations in Galaxy.
Gog-Connect is not dead.
Its just, that giving away free games as a developer (which is how GOG-Connect works) is not very popular. Therefore there have to be incentives (financial or promotional) for the developers to actvate GOG-connect, which is why it happens not very often.
It isn't some techy features which lacks support, but just an advertisment-tool which costs money, every time you'll use it.
