I don’t have a PS5 but my Xbox (my first one ever) is an absolute nightmare to play, even if I have the physical media. Still demands an internet connection. Still demands updates before I play. Typically I would expect to wait 2+ hours before I’m allowed to play a game I have on physical media. Often the estimated time is so long I just give up and don’t play. I let it update and then forget about it. Come back a week later and it says my system is out of date and needs an update before I play.
Not the same experience at all compared to N64.
