These lists in no way take account of ad revenue. For the average indie game ad revenue now makes up at least 50% of the gross daily revenue or if well integrated can make up 70 or even 90% if the game is an advergame like the Ketchapps one finger frustration games. There is still quite a lot of revenue in the market place, just like there is on web. You need to be shrewd and think more about business than just creating and releasing a fun game.
