Age matters little.posted by pasofol on April 8th, 2008 at 8:54AM
At age of 7-8 I was better at mario 1 than I am now as an adult and that's even if I played a week straight.
Remeber going to a friends place as a kid around that age and the youth there were having a problem with a level I did it running through without a problem. They were quite amazed by it at the time but it was nothing to me just another level.
PS: You can find a open source emulator and try it yourself. I'd be interested to see what people get within the first hour.
