I don't understand why GOG absolutely doesn't audit the games published on GOG regarding the post-publishing content, consistency, compatibility, and quality. The so-called "Curated Selection" should involve this.
Right now on GOG, there is totally no way to update many abandoned by developers games with the latest patches, let alone the possibility of buying the DLCs which have been released on Steam but not on GOG.
Example: Craft the World.
The game on Steam (currently 1.6.005) compared to GOG (1.5.003) is almost 2 years ahead with 6 patches, and +2 new DLCs one of which is free for Steam customers.
GOG within its store should at least mark these unsupported games with information clause, stating that this or this particular GOG game version is outdated and may not receive any future patches or additional DLCs - so the customer could make an informed decision before making a purchase. Or completely remove these game from the store.
I would rather see a thoroughly revised GOG policy which would put a strict responsibility on the publishers/developers by enforcing publication of game updates and DLCs on GOG at the same time as on Steam. And by demanding the publishers to support their games released on GOG (and their customers) at the same level as with Steam when it comes to game patches, released DLCs and published additional content such as language selection (text and audio), changelogs, achievements, goodies, user manuals, etc.
And if not, then at least allow GOG customers to transfer the defunct, incomplete and abandoned games from GOG to Steam at the cost of the publisher, by providing Steam activation keys, or issuing a special refund.
