Just to clarify this, Chernobylite has controller support on GOG as well. Screenshot attached.

The tags on game pages on GOG are highly unreliable. There is no reason for a game to have controller support on Steam and not on GOG, unless there are missing updates, and in that case the game is already on the list.

Thanks for the info!

And thanks for that info as well. Seems like this is a problem with the features list on the store page then.

Where do we report an erroneous game card tag without using external sites like Reddit?

Support - Account and Website. Problem type: other website issues.

Neither Ashwalkers nor Solasta - Crown of the Magister sell their respective soundtrack DLCs on GOG.

FYI, this issue is still not on the list yet.
(Patch Notes)

And yes, you can fix it yourself, but I'd like to see GOG do so first.

List updated!

It is now on the list!

I'm not sure if this qualifies but I purchased GForce Now a few months ago. It was a dumb purchase from the jump only made dumber by the fact that they dont include any GoG games that i've purchased in the available library. So even though Atom RPG is available to play on GForce Now, I can't play it because I purchased it on GoG and not Steam or Epic. Stuff like this sucks and really pushes people away from GoG.

Blame NVidia, I guess, for them ignoring biggest stash of legit vintage games in the world.
GOG games launched through this PlayNite plugin https://playnite.link/forum/thread-298.html are working absolutely well with GeForce Now.
It's just games, after all :)

I'm guessing this issue will not go on the list because that would require listing every single game on GOG :D

Seriously though, that is an interesting piece of information, thank you for pointing it out. I've had a look at GeForce Now's list of currently supported games and it looks like the only GOG games on there are from CDPR's own catalogue (minus Witcher 1). So it seems implementing support for GOG games is technically possible, but I'm assuming CDPR is the only dev who explicitly asked to also have GOG versions of their games added (that's assuming NVIDIA have to get permission before adding games to the service).

I corrected that for you ;-)

Geforce NOW requires you to own the game sure but it's still a bit ridiculous to classify such as "second class", less 3rd party integration and support for cloud streaming is only a good thing unless it will continue to push GOG more for such crap and only serve to water down the DRM experience here even more.

No it's a bad idea to list it here, sets a bad precedent and games that requires a 3rd party for some features already has.

Sir, You Are Being Hunted: updated to 1.5 on Steam last Wednesday. https://store.steampowered.com/news/app/242880/view/2977430785357902793

That's only a few days ago so it might just be working its way through GOG's processes. The game was last updated in 2015, when the Galaxy was young.
