Mawthra: Moonlighter should be updated... I have the game on both Steam and GOG and the current Steam version is at 1.9.19.0 while GOG is at 1.9.19.5... so it seems the GOG version got a small hotfix past the Steam version
(see attached screenshots I took in-game)
Cross-checked the source included in the sheet and the "What did just update?" thread, can confirm
Moonlighter was updated. However, it is not removed from the list as it is still missing the soundtrack.
Alexim: In addition,
King Arthur's Gold seems to lack many things: the two DLCs "Flags of the World Heads Pack" and "Fantasy Heads Pack", some localizations and probably even updates of the game itself. Someone who has the game should confirm it.
SCPM: The Heads Pack are paid cosmetic DLC, and they are not here/included. The game also has DLC only available to Patreon supporters. However, the game itself has an auto-updater, which I believe is the same for Steam, so the game is the same version on both platforms and gets any updates simultaneously. It even has a special message in Galaxy, 'UPDATES NOT MANAGED BY GOG GALAXY'.
So in a way, GOG users are treated as second class citizens in
- missing out on cosmetic DLC
And everyone else is also treated as a second class citizen if they aren't Patreon supporters (in this case, are the supporters backers of the game or is it a permanent reward for supporting the devs on Patreon?)
Interesting case here.
