Just watching a Gametrailers podcast from a few weeks ago and Brandon had a good idea for Amiibo in the absence of them not having their own game yet.
He said how amiibo needs to at least have it's own Miiverse plaza, with a hall of fame like Disney Infinity, where you can see statues of the ones you've purchased, their levels, which ones you are yet to buy, which games figures work with, all of which you can keep track of in this social space/hub. And you can move around the space in a Mii costume of these characters. Developing it further it could become like Nintendo Land with each character having its own game, which I think is something we're all hoping Nintendo would be doing with these as well.
