Sigh. I tried to get in contact with the devs through the official discord, but there are a couple users there who are ridiculously hostile to any mentions of GOG and shut down any conversations about it.

patch 1.05 is out for GOG now!

We can take it off the list now. Happy they updated the game!

fallout 4 second class gog ,new next gen patch no available

Northgard, it got updated yesterday on Steam with the release of a new DLC clan, but GOG build has not yet been updated.

This means GOG Northgard players can barely play online, since the game has a small player base and most of it comes from Steam. Until the GOG version gets updated, Gog customers can't play with Steam players.

These games are missing their soundtracks and should be added to the list:
• The Wild at Heart
• Unpacking

This is really strange, they used to be mostly on par with Steam.

I asked them to see is there's some news about it.

Edit: I searched in their Discord and the devs say the update and DLC will come is just gonna take a little more time.

Thanks for the heads up.

Apparently, the final "Fuck you" is that Spiderling (the developers) is removing Besiege from sale here.

Too bad, fuck those devs.

The logic is truly mind boggling. They've done just about everything in their power to drive users away from GOG (slow updates, killing 3rd party mod websites via Steam Workshop integration, etc.), and then act confused as to why it isn't selling on GOG.
Then, rather than try to make things right, they just double down on the behavior.

Looks like update just dropped for it today . We can take it off the list.

The Lullaby of Life Digital Deluxe Edition (artbook + wallpapers + soundtrack) is missing on GOG, while available on Steam.

Heart of the Woods is missing its paid Artbook DLC.

Wigmund got the Patch 1.4.5 same day as steam. So that means the GOG version is updated now.
