Let's say Iwata decides to hold an experiment and approve just one bite-sized mobile game based on a Nintendo property, either for iOS or Android, which game would you want it to be?
I think it definitely shouldn't be an immersive experience like Zelda or Metroid but something simple with arcade mechanics that can people can play for a few minutes just to be reminded how great Nintendo games are. A remake of Ice Climbers or Balloon Fight for mobile phones would be perfect for this purpose.
What other Nintendo properties would do well in a game like this?
