I think you hit it on the spot by saying Nintendo tapped into the women and older market. Proof of this is my wifes DS and interest in getting the Wii. She doesn't care for my type of games and rarely plays them with me. She does however cruise the DS and Wii sections, looking for new games. I'm just glad she is interested in general, which opens up the possibility of me getting new hardware and games. =) Very interesting article indeed, good job.
