How Nintendo sells DS units

The recent issue of Famitsu asks, "Why did the Nintendo DS sell so well?" in Japan. Here are the five
reasons according to the Japanese game mag:
- Great Promotions -
"A famous Japanese actress, Nanako Matsushima, appeared on a recent commercial for More Brain Training, and for
once the woman they dragged out to pose with a videogame actually seemed to be really enjoying herself."
- Demo stations were plentiful - "In any department store in Japan, there are DS demo stations.
Usually the screens are scratched to high hell, and lately, there are a lot of games to choose from."
- Appeal to non-gamers - "This is the most obvious reason."
- Wi-Fi
game download stations - "At any videogame store, there are DS download and play stations."
- Great games sold the system - "Nintendo has always prided itself in quality games and DS has
been a shining example. The quality of the games has caused developers to think in new ways, or to find
inspiration."
