Serious question - have you heard of God of War, Ghost of Tsushima, or The Last of Us 2 on PS4? You mention childish and these are like 3 of the top games on PS4 and they are all adult oriented. Then you got all these indie games including Blasphemous or Dead Cells, that I believe is on all 3 consoles. Go look up a trailer of Blasphemous and let me know how childish that game looks. It just seems like you are completely uninformed of what you are talking about. Again, not trying to be a dick but you just are not very informed of the library based on your comments.
And I do agree with
@cmdrdredd that the genres you are into simply do not translate well onto console. It's the same reason I stopped gaming on PC because the games I enjoy now translate better to console than PC. I used to love Starcraft, Diablo, and FPS games which are superior on PC control wise, but am just not into those anymore.
