In a way, piracy can fix that problem too, since pirate servers existing for ongoing games means they’ll never actually die

That happened to Ragnarok Online. Iirc the early server code got leaked by hackers (it seems it’s still being developed on GitHub lol), so all throughout the game’s 20+ years lifetime it has had a flourishing private server scene with hundreds of servers still online, so I don’t think it will die in our lifetimes.
