For those who don't know, amiibo are little figures of Nintendo characters (hope you know that much!) that you can scan on the Wii U gamepad or New 3DS XL touch screen to use in game! Amiibo have an NFC chip inside the base that systems can read from or write to. An amiibo can be used in read-only form with as many games as you like! However, each one can only hold save data from one game, so if you want to use Peach with both Super Smash Brothers and Mario Party 10 you'll need two of them (please note, even if an amiibo has save data written to it, it can still be used in read-only form with other games!).In Super Smash Bros. for Wii U or 3DS an amiibo can be scanned in as a non-player character for you to team up with or fight against! Your amiibo will learn from your play style and gain levels (up to level 50) as it learns, getting both stronger and smarter. Because it learns from you, no matter what your skill level is the amiibo will be a perfect challenge tailored for you! You can also feed unlocked items to amiibo to make them even stronger, and give them special abilities.On top of all that, the amiibo figures are actually very nice quality, given their price point! Sure, some might have minor paint flaws or something, but overall they are very nice figures. Great to put on display, and functional as well! Amiibo are very worth the $12.99 they cost and a must-have for any Nintendo fan!
