The data is surprising. However, I do wish this article looked carefully into barriers of entry as it can explain the lack of increases in your data.

For example, in Steam, it costs $100 to release a game. You may extend your game with what's called a DLC and that costs $0 to release. If I were to build shovelware with especially with AI-generated content, I'd more keen to make a single game with a bunch of DLC.

For game development, integration of AI into engines is another barrier. There aren't that many choices of engines that gives AI an interface to work with. The obvious interface is games that can be entirely build with code (e.g., pygame; even Godot is a big stretch)
