I am so down for this. I don't have the creativity or patience to sit down and actually create levels, so the lack of level sharing has literally zero impact on me. However, I love the 100 Mario Challenge, that's where the meat of the game is for me. I hardly touch Mario Maker Wii U, or really the console itself, anymore because of how much of a pain it is to load everything up. With my 3DS, I just open it up and jump right in. I am very much looking forward to a quick, streamlined Mario Maker experience.
