That's mostly the MBAification of games that I think is completely disconnected from what most kids want. But the MBA logic is about maximizing market reach. Relatively few people will choose not to play a game because it's too easy, but ostensibly the same isn't true of games that are seen as difficult. Of course Elden Ring, Dark Souls, et al completely proved this to be nonsense (to say nothing of pvp games), but who's gonna let a bit of reality get in the way of pie charts, bar graphs, and powerpoints?

In the world of games outside the big money AAA MBA stuff, there's plenty of highly challenging franchises that maintain true to themselves and thrive, even with plenty of kids playing. E.g. - I suspect the median age for Binding of Isaac is well below the age of consent.
