Aside from Super Smash Bros. for Wii U, Nintendo also announced a list of compatible videogames: Captain Toad Treasure Tracker, Mario Kart 8, Mario Party 10 and Yoshi’s Wooly World. The Amiibos have a listed release date on the 31st of December, which is obviously a placeholder. A more formal date should be announced soon.
For those unfamiliar with Amiibos, the interactive figures have a chip inside that could send and store data. It is similar to how Skylanders and Disney Infinity function. This opens up some possibilities when it comes to new and creative ways to play a videogame.
