I think Miitomo is going to function very much like Rusty. What they showed off is the free, social part of the app. The paid stuff will likely be Rusty/Streetpass-like mini games you can play with your friends. If I'm right, this is a really good idea. It's my idea of a Words With Friends-like app, but with multiple games on one app.
If each game is like $0.99 or something, this could be big.
