It’s a cool feature and some old games are timeless. But what’s stopping you from playing them right now on the consoles they were made for? Your PS4 works I assume. Not sure about the others you got because gamers end up selling their old consoles assuming the new one plays their old games. Like my PS3 digital games not being compatible on PS4.
And why is Nintendo always excluded from the conversation? How come my old floppy discs don’t work on my new computers?
Eventually, some old tech and old software are going to no longer be compatible unless we digitize everything and update the old software repeatedly. But even then, something’s got to give. I have a new phone. Some of my old apps aren’t compatible. And on my older tablet. Some of the apps that did work got updated and no longer work on my tablet.
Basically who’s going to keep spending the money, manpower and resources to keep updating everything so it’s not lost to history and for how long should they do so?
I’m all for preservation. But nothing lasts forever.
