Nintendo has never and probably will never try and seriously compete in the multiplayer arena - they've got some casual multiplayer stuff but they're not trying to out compete Call of Duty, Halo or Starcraft.
I do agree that they do milk those main properties for all their worth, but they're pretty careful about releasing bombs - Mario Odyssey was a pretty notable and dramatic fail for them but, again, the fact that their games suck to you doesn't matter. I'm a big fan of EU4 and as such Nintendo doesn't want my business - they cater to young and casual audiences building easy to access for the family games rather than historical simulators or Dark Souls.
