I’ve had the opposite experience and was actually referring to this generation in my comment, specifically for the series X.
With Xbox 360 and even some Xbox one games, I was able to come home with the game and put it into the console knowing I could play it right away from the disc (or install for the Xbox one and play). When I buy a game now, referring to physical copies, I’m unable to play without requiring internet. I understand some games have limitations on disc size, but once upon a time, that’s where multi disc came in. Just the other day I forgot to unplug my console from the network to play a game and was hit by a firmware update request that I couldn’t say “later” to. Once that finally finished, I unplugged but I guess the console already got wiff of an update for the game I wanted to play and said I need to be connected to the internet to continue.
This is definitely not something I ran into with older generations, personally. That being said, it sounds like your experience was different, so I suppose mileage may vary
