I think most artists want an audience, and that requires skills on the business side. Having a successful business also pays to create more art. I can't help you there!
If you look at the app store top 100, there aren't that many "fun" or original games up there. There's even a tonne of idle click games! I think one thing that's important to recognize is that most people playing mobile games don't see the experience as a 'game'. It's more of a passive ride to distract themselves for a few minutes. Idle click games aren't fun in a traditional sense, but they have isolated a reward feedback loop in your brain and serve some function to make its users enjoy the experience.
I didn't work at Zynga on game design, so I'm not here to defend corporate mobile game design. However, I don't want to knock the business side of things too much either. I learned there's a ton of creativity in creating new hooks and game modes to increase engagement/spending. Games constantly riff off each others game loops and it's a very quickly evolving field. There's also lots of room for creativity in making successful advertising campaigns.
