I have a Nintendo DS. I bought it to play the Brain Age games and similar games.
I'm not a Super Mario Brothers type of gameplayer.
I sure do wish they'd create more games for adults, like mystery games (not those seek-n-finds that claim to be mystery games) and quest games. I just can't play games with little anime cartoon characters. There was supposed to be an emergency room sim game, but I was never able to find it.
