For all Steam’s faults…they host games forever it seems. A game I use to play was pulled from the storefront but stayed in your library(assuming you had it prior) because the publisher shut it all down back in 2017. I can still download and launch the game but the servers were gone so you couldn’t really play. Apparently pretty recently people found a way to get bootleg servers up so players were appearing as online again.

I’ll agree it’s still a point of failure if Steam just up and disappears but I’ve never had a game actually disappear from my library yet. Unlike basically every digital copy platform for movies (digital copy codes from physical copies). Just because you ‘own’ a digital movie doesn’t mean it won’t just vanish one day. iTunes will generally give you a couple bucks if you bring it to their attention that it’s gone but other platforms basically tell you to pound sand.

We basically have the exe issue with PC games on disc. I’ve got a few of those but most have been community patched so you just copy the cd contents, copy a file or two on top and launch the game for a modern os. Obviously some security risk here if those patched files are malicious.
