Wired Magazine reported this in 2013:
During a Q&A session, Satoru Iwata revealed why Nintendo’s newer games are easier. Nintendo conducted a test with many gamers and found that most of them were unable to finish the first level in the original Super Mario Bros.
...
"It may come as a shock to some of you that most gamers today can not finish the original Super Mario Brothers game on the Famicom."
...
"We watched the replay videos of how the gamers performed and saw that many did not understand simple concepts like bottomless pits. Around 70 percent died to the first Goomba. Another 50 percent died twice. Many thought the coins were enemies and tried to avoid them. Also, most of them did not use the run button. There were many other depressing things we noted but I can not remember them at the moment..."
Is there any truth to the claim?
