Just found out Trek to Yomi is missing the latest patch 1.03 which was released on Steam on Feb 2nd 2023 / Latest one on GOG is 1.02 on June 6th 2022 (even though the version on GOG lists 1.007).

The Last Spell

GOG: current version is 1.1.3.4 (18 July 2024)
Steam: has received at least 5 updates from November 2024 to January 2025; current version is 1.1.6.2 (14 January 2025)

The patch is now here, we just need the soundtrack now.

Vambrace: Cold Soul finally received an update today:

Will be buying the DLC now.

Dome Keeper: Assessor Gear Pack
Dome Keeper: Engineer Gear Pack
Dome Keeper Soundtrack

are now available on GOG. :-)

Mac and Linux versions are left behind as usual. Nothing changes for me.

The GOG and VCS releases of "Atari 50: The Anniversary Celebration" will not be getting any of the promised DLC, as per Atari's latest update. Despite being the owner of the IP, they're passing the blame to the developer.

A source reference is always nice.

Apparently, a discord announcement:

Thank you!

That's bad news. I bought it right after the DLC was announced and precisely because the DLC was supposed to be released here. Now I feel like I've been ripped off and will wait even longer from now on until DLCs for games are actually released here.

Maybe not all hope is lost yet. It seems that a staff member from GOG (Jed) will contact Atari to try and find a solution.

Hope dies last :)
