Wow! Math on the DS! My children will be so addicted to this game that they will be able to get good grades in schools...NOT!!
Okay, there have been way more than enough edutainment games for the DS.
Most of them are crap (Except for the My [Insert Language Here] coach games) and need to be killed. They are educational, but they are not entertaining.
How about Nintendo publishes a REAL edutainment game...MATH BLASTER! I loved to play MATH BLASTER all the time at school! I beat that game like 10 times on the hardest difficulty! I got good grades on math too! Now THAT is edutainment!
