Your Brain on Video Games

I found this video full of interesting statements and statistics. I was not surprised that the average age of a gamer is 33 years old. This is the generation that saw the rise of Atari, Nintendo, Sega and Playstation. This generation grew up with advancing game technology. Three additional things that really caught my attention were:

• 90% of children play video games - This surprised me. I don't disagree with this statement, but I question its validity. Is this just in the United States? I would like to hear more about this statistic because I can't imagine 90% of the world's children having access to video games.
• Call of Duty: Black Ops logged 68,000 years of playing time in its first month - This does not surprise me. My husband heavily contributed to this statistic. Wouldn't it be amazing if that much collective time was put into something productive...like solving world hunger or cleaning my living room?
• "Screen time makes your vision worse" is just a myth. This didn't surprise me because action games are like eye exercise.

According to the video "Your Brain on Video Games", action based video games increase object recognition and improve your eyesight.

Question:
How can we make an action-based educational game that students would enjoy playing?
