GOG have announced a new feature today, which they are calling GOG Connect:

Today, we’re launching a new program called GOG Connect. The premise is simple: connect your Steam account and add your eligible games to your GOG.com library.

Whether you’re checking us out for the first time or have been with us for a while, GOG Connect gets you DRM-free versions of your games, digital extras, and a whole lot of freedom of choice (like whether you go with the GOG Galaxy client or not). It gets you our take on game ownership, and we say: why buy the games more than once?

Thanks to our awesome partners including Deep Silver, Harebrained Schemes, Jonathan Blow’s Number None, TaleWorlds and more, you can now add more than 20 games to your GOG.com library if you previously purchased them on Steam.

You can find a list of all eligible games here; there aren’t that many at present, but presumably the list will grow over time. However, it is worth noting this caveat on the page:

You’ll be able to permanently import all the games listed below to your GOG.com library – assuming you own them. The eligible games are limited-time offers made possible by participating developers and publishers, so stay tuned for more games to come.

Additionally, if you have more than one Steam account:

You can connect only one Steam account with your GOG.com library. This process is permanent – choose wisely!

GOG Connect kind of seems like it might have grown out of GOG’s Reclaim Your Games initiative. Anyone remember that?
