GOG Connect is a new service launched by GOG.com to enable users to connect their Steam account and copy across eligible games to their GOG library.
"Whether you're checking us out for the first time or looking to copy over your previous purchases, GOG Connect gives you DRM-free versions of your games, along with digital extras and the freedom to choose between standalone installers or the optional GOG Galaxy Client," explains GOG. "It's our take on game ownership and we say: why buy the games more than once?"
Titles currently supported include The Witness, FTL, Trine Enhanced Edition, Saints Row 2, Shadowrun Returns and more. Over 20 games can currently be added to your GOG.com library, with more to available in the future.
Be aware that the ability to copy across titles is time limited, so be sure to make the copy as and when your games allow it.
"While GOG Connect will stick around, the games available will come and go. These are limited-time offers made possible by participating developers and publishers, so stay tuned for more games to come," explains GOG.
You'll find a complete list of currently supported games over on GOG.com.
