Nintendo will be shipping the retail version of Super Mario Maker with a detailed booklet which includes a bunch of design ideas for the game. But even if you buy the game digitally on your Wii U, Nintendo, being the constant good guys in the gaming industry, will mail you a free booklet.
In order to receive the free Super Mario Maker booklet, you have to call Nintendo on a toll-free number found on your digital receipt, and let them know that you would like to receive the booklet. After you’ve given them your Wii U serial number and your contact info, Nintendo will ship the booklet to you, free of charge, when the game launches.
It’s little things like this that make Nintendo awesome.
