This was brought on by the Sony news that all disk based distribution will stop.

At what point do I have be concerned that a cart or disk I buy won’t work on my system without a mandatory download?

The ps3 seem pretty clear but I seem to recall a game or two that did require a download, or system update, to play.

How many ps4/ps5 games would I be able to play without a server connection?

What about switch 1 /2 games?

Is there a website that tracks this or a way to tell?
