If Mario Was Designed in 2010
In an interview between Miyamoto and Iwata the genius of this first level is discussedhttp://us.wii.com/iwata_asks/nsmb/vol1_page4.jsp"But if you avoid the first Goomba and then jump and hit a block above you, a mushroom will spring out and you'll get a shock. But then you'll see that it's going to the right so you'll think: "I'm safe! Something strange appeared but I'm okay!" But of course when it goes against a pipe up ahead, the mushroom will come back! (laughs)" ... "At that point, even if you panic and try to jump out of the way, you'll hit the block above you. Then just at the instant where you accept that you're done for, Mario will suddenly shake and grow bigger!"It turns out they panned it so you cannot avoid picking up that first mushroom that makes you big. They expected the first players to see it as an enemy, so they wanted to trap you into picking it up and then showing you that it made you more powerful.Barely anyone notices that this was forced, but now everyone takes it for granted that the the mushrooms are good!
