>These Game Key Cards are an entirely new thing
They're not, it's been happening since at least the middle of last gen. Simple example is literally any Xbone game that says it has a Series version. The physical disk is almost always only of the Xbone version and the Series version is only downloadable. Assassin's Creed Origins, Odyssey, Valhalla, Mirage, Gears Tactics, Gears 5, and Halo Infinite are examples of this off the top of my head. I've only ever seen Spongebob Cosmic Shake be a counter to this where it was the actual Series version with no download despite being an Xbone disk.
If you want to point at other games then the Spyro Reignited Trilogy does not have anything other than STD on the disk. RR and YOTG weren't even finished when the disk went gold so those only exist as part of a digital download.
The Switch version is even worse despite coming out years after the fact. It only has the first world of each game on the cart and you have to download the rest of each game.
THPS1+2HD are digital only, your physical disk is just used to tell it to download the data, there is no actual playable game on it.
All of the more recent Call of Duty games are not on the disk at all, it's like 30-40GB if I remember right and you download the 100GB rest before you can even play it.
One of the more recent Doom games makes it so the disk is only a download for the game and the actual file on the disk is like 1 MB or something like that on both PS5 and Series.
Indiana Jones (Both Series and PS5) and Starfield are just disks that tell the system to download the game like Doom. There is nothing on the disk.
Hogwarts Legacy, even the more recent backported PS4 version, only has around 38ish GB of data on the disk and only allows you to play the tutorial. Once you get past the tutorial (I.e. reach Hogwarts) it forces you to download the rest of the game.
