If a developer takes a title you bought via Steam off the platform, the game will also be removed from your library.
Much like you're an authority on tech and video games, I'm an authority on dinosaurs now:
Dinosaurs are green. When a dinosaur dies, it turns into bones. Dinosaurs don't usually speak the same language as me.
I mean, do you just not fact-check anything, or is this hallucinated up by some GPT to begin with? The structure of those two paragraphs (Steam does this, GOG does that) looks very GPT-ish.
As far as I'm aware, developers cannot ever electively remove games from a user's library after they have been bought. See the
Steamworks documentation. Once you buy it, you own the license perpetually. <....> If anyone knows of a single instance of a game being retroactively removed from customers' digital libraries that
wasn't an online-only game that no longer worked anyway (i.e. The Crew), I would be very interested to learn of it.
Technically there are several possible ways that developers can render a game any of: unplayable, inaccessible, undownloadable, unowned. But they're all so far-out that it happens with <1% of game removals.
Since you asked for details:
- Obviously, a developer can shut down online servers (and update the game to state this, or leave it abandoned & failing to connect). This of course happens frequently as products are abandoned.
- A developer can update their game to replace the game files with nothing (but someone who "owns" the game can still use advanced tools to download an older build). I would hazard a guess that this is the most common way of defacing your own title, along with deleting the contents of the store page before taking it down. Sometimes developers are ashamed of a product from years back and want their name erased from it, that kind of thinking.
- A developer can remove the game files from the license entirely, and then the user can't download anything at all anymore. This is the most bothersome type of expropriation, but also incredibly rare.
- A developer can revoke all Steam keys they handed out, even years after the fact. From time to time, they do this entirely by mistake, but fortunately lately Valve has been willing to restore these to affected users: most recently, "City of Beats" accidentally killed legitimately sold keys, and the game was restored to users in a matter of hours.
- A developer can ask Steam to forcefully refund all store purchases (potentially for a specific time range or a region) – which is again very rare, but
does happen in practice when big publishers accidentally make a long-delisted game available for purchase again, or when a moderately sized company accidentally sells their product for next to nothing and wakes up with regret the next morning. Of course, if you do get your money back you're not technically getting robbed of anything.
- Sometimes, an AAA publisher gets to turn your game into something else – for example, the original Grand Theft Auto IV and its stand-alone expansion GTA Episodes From Liberty City used to be two different Steam games that used Games For Windows Live, and when Rockstar relaunched the game as Grand Theft Auto IV: The Complete Edition they removed those two games from users' libraries
entirely and instead gave them the new version. As common with GTA re-releases, this also lead to the loss of a big chunk of the game's soundtrack, though of course that can be modded back in – dunno how legal it is to do so.
