You have MAME and other console emulators with thousands of games, but how much of them are present on today's culture?
There is no survivor bias, you [insert insult]!
So many of those games were really bad even at their time. BUT YOU CAN STILL PLAY THEM. I've tossed many games out of my catalogue and for some I wished they vanish from existence and they all have survived!
While article is recycling narrative - it has a reason, but your recycled opinion is not only wrong but has no reason other than lowkey nitpick article.
That is one way to die, like a random book written 100 years ago that never became a classic and even if you can find a copy, it doesn't count as existing anymore for the current culture. A game that had enough players and cultural mindset, but that because the maker, the servers it used to run or whatever don't let them be played anymore can spawn copies and lookalikes with different names and get some player base, it is a different kind of death.
