Everyone's talking about demographics in terms of age. Well theres another category that has a huge amount of potential: girl gamers. It seems that Nintendo's targeting them specifically for the NDS. The japanese ads both feature a female using the device. It's also more hands-on (literally) than just about anything else in the market right now. I know know very few girls that are into gaming. But those who do generally like DDR and puzzle games. The DS definitly fits this kind of criteria. Just a thought..
