My youngest ds is 3years old and HE plays GB color. My oldest ds, 7, has GB advance. I was thinking about buying another "advance" for the younger one when we go to WDW for the plane ride. I'm hoping that they will come down in price a little.
My little guy also plays Nintendo 64, if you could believe that one. He's really good, too. Better than me. Sometimes he beats his older brother.
They're really good for rainy days and long car trips.
TTFN,
Maria
