GOG has had games that fail to maintain parity with Steam releases.
GOG requires workarounds on Linux moreso than Steam.
The first is not totally GOG’s fault but they should take action. If GOG is truly about preservation, they should make Linux a priority.
My second biggest gaming library is GOG. I love them in theory but Steam wipes the floor with them in terms of who gets my business in part because of those.
