What are you talking about? How is this different from any other mobile game? And since it's an always-online game, what happens if they shut off the servers?
While it's true that few mobile games can have that broad kind of appeal, it is like many others in the fact that it has an in-game currency--purchasable with real money--that can be used to buy consumable items. These games will continue to rule the highest-grossing charts.
Super Mario Run will fall off the highest-grossing chart much more quickly. I'm not knocking it, it's just that people will either buy it or not, and then there is no more reason for anyone to spend money on it. I'm kind of shocked that the game was released in this state, where it's 100% complete and doesn't seem to leave the door open for paid DLC to be added on a regular basis. That's completely the opposite of most mobile games in 2016, especially the popular ones.
