Nintendo recently sent out a press release where they went over the latest numbers for their popular brain-trainer DS title Brain Age: Train Your Brain in Minutes a Day. In revealing the numbers for the three major regions of North and South America, Europe, and Japan, Nintendo stated they have sold over 4 million units worldwide. 600,000 of the units were sold in the Americas, 500,000 total in Europe, and an insane 3 million units have been sold in Japan.
"Brain Age is so easy to pick up and play, regardless of your experience level," says George Harrison, Nintendo of America's senior vice president of marketing and corporate communications. "You can play it for 10 minutes or an hour and keep yourself feeling sharp. As a baby boomer, it's like a treadmill for my mind."
