What is fun for you may not be the same as what is fun for someone else.
I would guess that many people gauge fun on weather or not they are enjoying themselves while they play the game.
The business end of the game is an afterthought to them if they even think about it.
Yes some people do want something mindlessly easy which is why so many games have a creative mode setting (3 that come to mind Minecraft, 7DTD, NMS).
So no I really don't think the things you are most concerned about have a darn thing to do with which game many people choose. All they care about is if they are enjoying themselves.
