There's a bit of bad news for fans of DRM-free gaming: there will be no official GOG Steam Deck support -- but that doesn't mean it won't be possible.
You're probably aware of the Steam Deck by now: it's a handheld gaming PC that was first revealed last summer. It's looked like a pretty robust device at first glance -- as one might expect, it pretty much sold out in no time flat.
Part of the Steam Deck's appeal is the growing library of games that will be available to play on it, combined with its integration with the Steam ecosystem. Unfortunately, that list of games won't include anything exclusive to DRM-free gaming retailer GOG -- at least, not officially.

GOG Steam Deck Support Should Still Be Possible
While the news of there being no official GOG Steam Deck support is a bit of a downer, it may ultimately end up being a minor inconvenience as highlighted in a tweet from the company (via ResetEra).
"There's no official GOG support for SteamDeck," read the tweet. "But since the device has an open architecture, as we understand, you can install Windows and as such also run GOG games."
Indeed, the Steam Deck's flexibility in allowing you to install other operating systems is one of its key highlights. Since GOG Galaxy runs on Windows, that means that you should be able to get it to work on a Steam Deck running Windows instead of the default SteamOS. That wouldn't be the only option, though -- as this ResetEra thread highlights, there is a neat program called Lutris that would allow you to run GOG (and several other game clients as well, Steam included).
The true scope of what's possible, however, will only come to light once the Steam Deck has been in the hands of the public for a while. We already know that the Wii and GameCube emulator Dolphin can work on the Steam Deck -- goodness knows what other cool stuff will be running on the Steam Deck in the future, officially or not.
