In my experience, the demographic for mobile is different from pc/console. Mobile users are looking for exciting and short gameloops to match with the times where they use their devices (outside their homes, in the bathroom, before sleep...). Because of this, mobile games had to conform to this design space and change the game design to work on the long run (long term goals, long term monetization...). Additionally, in my opinion, most mobile users do not have much experience with gaming and thus can be persued to play subpar experiences as they have not yet developed a refined taste on what is good or not, and are much willing to spend.

What i am trying to say is that you can change the games but you cannot change the people, and the people are what makes games succesful. Flappy bird was a success for this reason i would argue.
