10. Super Mario 3D Land

Developed and Published by Nintendo

You see, Nintendo? All it really took to prove that the 3DS was worth its weight in money was a true first-party game. SM3DL is the first system-selling title for the little handheld that isn't a straight up remake (see: Ocarina of Time 3D, Star Fox 64 3D), and it's freaking fantastic. Riffing off Mario Galaxy 2, it's got the perfect blend of 3D and 2D gameplay. It even brings back tons of classic Mario elements, the beloved Tanooki suit being of particular note. And thanks in large part to its often-vertical level design and clever use of space, the 3D display actually makes the game more awesome instead of just giving you an eye-ache.
