Nintendo is aggressively pushing video content out for Super Mario 3D World, and you know what? I'm completely ok with that, given how amazing the game is looking right now. The newest clip is the "Nintendo Minute," which is basically a Let's Play of more 3D World stages.
The folks over at Nintendo will go over stage 1-1, which has been shown many times before, as well as World 3, a winter wonderland of sorts. Along the way you'll see a ton of multiplayer specific features, like the crown that goes to the player who is currently ranked first.
