Is a good idea to release something like this for free, since looks way more interesting than Amiibo Crossing, people has already a lot of Amiibos and it would push the console sales at launch. It would be also cool if they gave you something with the NX that allows you to buy one amiibo that you want (or the amiibo you can find in the stores that you want) for free too, so you can play the game even if you don´t have amiibos.
