The majority of games released on disc, even today, are playable by putting them into a console, installing, and playing. No internet, no downloads.

There may be debate about “full games” given day one patches and future content updates, etc, but it is a misconception bordering on misinformation campaign that games these days don’t ship on disc.

They do. Final Fantasy VII Rebirth, for example, has so much game shipped on disc that it came with two.
