Maybe I’ve been lucky but I didn’t see AI garbage games in Steam yet.
However, ultra low quality copycats or “XYZ Simulator” with barebones scenarios and basic assets have been flooding Steam for years.
The adult category is even worse, very badly made games, some clearly being taken from a tutorial for learning the game engine, sparkled with some few hentai images in the background and sold by a very low price.
Nintendo is pushing for digital very aggressively in their marketing to gear people towards digital only.
Give them a generation or two more and you’ll have them doing the same shit Sony is doing now.
