What does getting "delisted" off Steam means for games I already own?
Recently I've seen news about adult swim games going delisted probably off steam, one of my fav games is published by adult swim games and I want to know what will happen to it, will steam strike it off my list even if I have it installed? Will I still be able to back it up and restore its backups? Will I still be able to matchmake through steam?
I don't know about this case specifically, but I own Alan Wake on steam which has since been delisted because of music licenses running out. At least for that one, I still own the game on steam and can download, install and play it normally whenever I want, it's just that people cannot buy it anymore through steam. If you're lucky, it's gonna be the same with the adult swim games.
Alan Wake is actually back on Steam! Remedy was able to work something out with the music rights (the reason why it was delisted) that put it back on virtual storefronts.
Nothing changes for you, if you already own them. They'll still be in your library like before. Visually, the only difference will be that those specific games will have no store page
Obviously in this case, no more updates. If there's a server, it's getting shut down. And no new players will buy it. So player count will decrease until it's a dead game, even if multiplayer is peer to peer. But I doubt that's the case.
You can't see the store page anymore, that's it. I know because I own a delisted game that I don't even remember when/where I got, an astronaut FPS in zero-G asteroids or something. I can still install and try to play, can't actually play because it's multiplayer only and servers are dead.
