Only 10 days have passed since Super Mario Run was released which is not even two weeks. But seems like Nintendo has a plan for Super Mario Run 2.
Nintendo appears to be asking fans about the possibility of Super Mario Run 2 through polling. While the game is on a rampage with up to 40 million downloads worldwide but looking at what Nintendo is doing the next Mario game will not be far away.
The game is not free, you have to play $10 to unlock the full game though you can try the demo. The game is currently available on iOS devices and might become available for Android in the near future.
