I saw the commercials for these. I was so intrigued I went out and bought a Nintendo DS and the "game".
Now, I'm going to say I was disappointed, but it has nothing to do with the quality of the program. I just had unrealistic expectations. For some reason, I was thinking it would cover some more advanced dishes ala the Hell's Kitchen video game (yes, there are actually top-end recipes in that program). What I ended up with was a lot of basic recipes that aims to make cooking fun for younger people.
There's nothing wrong with that--it does what it does and it does it well--it's just not what I was hoping for.
