People are willing to play complete garbage that they get absolutely nothing from. There are no memories there to tell their kids about. Like when you're 60-years-old and your grandkids are asking you about the games you played when you were young, are you going to say you played Farmville for months and months and wasted hundreds of hours of your life playing it? I think deep down most people know how counter-intuitive that is. I would much rather have a really quality short experience than waste my time on something that's okay.
