I'm pretty sure it's just exposure and time. Mobile is a great format for keeping yourself entertained on a subway. Desktop or console is a great format for actual games. People have more phones now because you need phones and you don't need desktops - that has nothing to do with the enjoyment you have gaming on each.

You used to be able to dial TIM on a landline phone to check the time (for free?). Then you (if you were a computer nerd) checked it on your computer, then on your cellphone. Because that's what was available. There was no connection between knowing the time and landline phones - people just had landline phones so it was a convenient way to deliver the service. That's how it is with mobile games now.

Remember Java and Flash applets? You could make anything you wanted as a native application, but RuneScape took off because you didn't have to install it.
