In case any of you don't already know by now, I have a very strong love of Nintendo games and have a fairly large collection of Nintendo memorabilia. Everything from games, to TV shows, to comics and even toys. But when I heard about amiibo, I nearly lost my composure at the possibilities for new styles of gameplay while also supplementing my insatiable craving for all things Nintendo. These little toys which are outfitted with NFC technology can interface with a chip reader embedded within the New Nintendo 3DS XL and in the Game Pad of the Wii U, but what they specifically do changes depending on which games they are compatible with.
Depending on the game in question, amiibo can do a wide variety of things. Some examples include unlocking costumes in Mario Kart 8, activating a new game mode in Captain Toad: Treasure Tracker, becoming your game piece and memory card in Mario Party 10, or even act as an AI controlled character that you can customize and train in Super Smash Bros for 3DS/Wii U. Think along the lines of amiibo being DLC (Disc Locked Content) wrapped in a very nice figurine, but that's not exactly the case for amiibo tap.
Now because of how new this app is and because no-one knows whether or not more game demos will be added to it in the future, it's only really best used as a "try before you buy" type program, but you can't really "try" unless you have enough amiibo to unlock everything so you can play them "before you buy." All in all, it is only really good for people like me and have a large collection of amiibo to use. Maybe you'll get some amiibo yourself so you can use this app, but until then, I'll be seeing you.
