Making a lot of small free to play games for mobile

Mobile games seem to be getting simpler and simpler. It makes sense, people don't play the game for very long and most of them are used as a distraction. 

What if, you made a lot of free to play games that took about 20-30 minutes to beat? It's free so most people won't care about the price and you get your app out the door. If you have links to your websites and links to more games, people will come back for more. 

On top of this your total app store download count goes up with every free game released.
