There are dozen of games that made headlines 5 years ago that you can't play today because servers are down. Some of those games are single player only.
You can't host these games like you could Quake or CS back in the day, because you never owned them in the first place.
I own couple hundred games on Steam and similar ammount on Epic but when I die no one will find an obscure CD_ROM in the attic that will urge them to find an old system they could try it on. My accounts will likely be wiped out after short period of inactivity.
Carmac made a historical move when he hosted a Quake tournament and offered his Ferrari as a reward, because he cared. Or maybe he sold his soul and the devil told him that esports will be a thing in the next 10 years. Point is - developers cared. But today, with the mcdonaldization of the industry you have countless situation like with the recent Rollerdome. Game had a stellar reviews but it didn't matter, because the moment before the game was launched the whole studio got sacked. Every single on of them.
Sure, we had issues in the past, the famous "spouses of Maxis employees vs Maxis", but today it's on a whole new level. People are naming their companies "Respawn" to indicate that they still have willingness to fight the system. And google how it turned out for them.
And then, when you finally thought there's a light at the end of the tunnel you have an endless stream of vaporware on kickstarter or projects that are - like Tarkov - for 8 years in "early access" (hey, don't be a dick, sure it's rough around the edges, but it's still in beta, bro).
All in all it was fun and games, but now it's a multi billion business now.
I've spent some time in the industry and when asked I always say it's a great adventure if you're young and have no major obligations, but god forbid you from making that your career choice.
