It’s probably more accurate to say Sony is misrepresenting the data.

The vast majority of games that get released these days are digital-only, indies, or semi-indies that never get a physical release in the first place. And it’s not reasonable to trust that Sony isn’t including these purchases in their reported stats. If they were giving us figures that included only games that got a physical and digital release, I imagine the narrative would be different.

The gaming industry wants licensing to be universal and ownership to be a thing of the past so it’s easier to price-gouge as they like.
