For whatever reason people seem to prefer colorful/cartoony games on smaller screen portables it seems like.
Even look on iOS/Android ... many of the top games have cartoony art styles that would be right at home in a Nintendo game.
For consoles, especially on the big screen, people seem to prefer more realistic graphics and they also expect a wider variety of content.
You can't wholesale be missing key genres/big 3rd party franchises on home only console. But on portable people are more lenient on library, if you don't have a Call of Duty or Madden or something it's not a big deal. On console though people want the variety and Nintendo has struggled with that since the SNES era.
