Something felt strange about those six different augmented reality cards that were revealed in GAME’s unboxing of the 3DS. It just seemed to good to be true that there would be five games based around classic Nintendo characters. And it is too good to be true. As clarified by the guy who unboxed the 3DS

"The ? card launches the program in AR games. You’re then given six options for six games. One of those games places Miis into the real world. You can move them around with the stick and change their pose with face buttons. Sadly there’s no animation – it’s like static statues. You can also move around in real space to change the angle of the look you have on them, and then take photos of the Miis. There’s also a program which lets you do the same. All those cards do is bring Samus, Kirby, Mario etc out into the world. Again – static statues, and you can change their pose with the fact buttons. You can also take pictures. I managed to get all the cards/characters to appear at once, which I thought was quite cool. There’s some cool sound effects from their games when the characters appear, too."

So yeah, it’s just for taking pictures of posable Nintendo characters. That same person also shares that one of the AR games we are yet to hear anything about is “basically a Billiards style game. It warps the ‘terrain’, puts obstacles in your way, and then you’re positioned behind a ball. You move around the ball to aim, and hit A to hit the ball – you have to try to hit a target that is around/past the things in your way.”
