Can mean anything (or more exactly anything that can be DRM-free and offline, (public) achievements have a separate list, and other clearly online features also shouldn't be included since they by definition can't be in GOG's DRM-free build). If a game has something on another store and it doesn't on GOG, it's 2nd class citizen treatment here.

I'm still saying : achievements is the cancer of DRM free gaming and it's holding back more releases in here .

Ah, so Blasphemous 2, not 1 like Ghildrean hinted

Oh, it was the first game? That OST doesn't seem to have been updated since August of last year. It does look like it increased 42 MB in size at the time, which would indicate more tracks added. Maybe it's been undiscovered for over a year?

I'll edit/correct my post above.

Not sure what is the problem here, but the first game has all the same tracks as on Steam.
39 tracks in total.

Edit: Just checked Blasphemous 2 and the DLC gives you the new soundtrack.

Edit2: Having said this the list needs to be updated!

I meant Blasphemous 1. For a long time the OST available here was only 27 tracks long and it seems it took them nearly 1.5 years to include the missing tracks.

It's one of the cancers infesting all gaming. Still, well said.

Can somebody check SpaceBourne 2 ?

I was told it is now up to date.

Seems like it.

We can thank Microsoft/Xbox for that as they invented achievements and made gamers addicted to getting points and shiny pictures for doing useless things :) And they are also the one who created the first online client in gaming (Xbox Live)

Also this does not just apply to GOG games too. If you play on a Nintendo console... you don't get achievements if the game does not have in game achievements even though it has client achievements in the PC/Xbox/Playstation version, because Nintendo consoles does not have a achievement system.

Yono and the Celestial Elephants which is marked as "Missing Simplified Chinese text" received its 01.01 CN update on 2020-08-05. There's now Chinese Language entrance available when downloading the game.

Asterix & Obelix XXL 3 - The Crystal Menhir's paid DLCs are no more missing, Viking Outfit, Legionary Outfit.

No DLC for Atari 50 Anniversary Collection when it has been released everywhere else

According to this post it will come here. But it seems weird that it's coming early 2025 and not for example next week.

GOG treats all customers as second class citizens, removing games from our libraries when they claim to be pro game preservation.

What game did you have removed?

Edit: You're the one who keeps saying that Spec Ops has been removed from your library. You probably purchased the game from a key reseller. Because several users, including myself, have confirmed that we still have Spec Ops in our libraries. So please stop spreading misinformation, or contact GOG about your missing game.
