You lost me there. Itch aint youtube with the content farms that mass produce shovelware clickbait.
Content here is not monetized by existing and generating traffic. The games do not make money by being on Itch, so there is no leverage to spam low effort things.
People vote here with their purse. If they like something, they buy it or "donate" to the project. So if they give money to a project involving ai, that is what they want. For whatever reason. Possibly because it is a good game and the ai is either seen as an enabling factor or actually looks good enough, because effort was put into it. Yeah sure, some naive people put out cookie cutter template games with ai slop and hope for some pocket money. But do they get it? Does such slop appear in here? https://itch.io/games/top-sellers
I do not know the threshold to appear in that list, but over 90% of the games here do not make it. And I have an inkling that anything "slop" is usually not in that list. No matter why it is slop.
