Not a huge
amount of detail has been given as
of yet, but scanning Animal Crossing
amiibo cards will make villagers appear in your town for a visit and some will even move in permanently (presumably villagers that don't have Special
cards).
2015 brought an immense
amount of marketing to the franchise, from
amiibo cards (used with the 3DS spinoff Happy Home Designer) that invoke memories
of those Game Boy Advance eReader
cards that were incorporated with Wild World, to its own
amiibo figure line (used with the less - than - well - received
amiibo Festival game on the Wii U), to an appearance in Mario Kart 8.
