Best selling non Nintendo published game on DS is Cooking Mama

[reverie]

I don't think Cooking Mama is the best 3rd party game on DS.

The Others figure of 1.43 million might be too high. 505 Games (the European distributor) announced 1 million Cooking Mama games sold by Dec 2007. That figure included 3 different titles: Cooking Mama 1 and 2 on DS and Cooking Mama on Wii.

Going by this, I would estimate sales for the original Cooking Mama in Others at 800k max, which puts the total at no more than 1.8 million.
