The difference here is that what you define as quality is according to a criteria outlined by a small elite, whether they be gaming reviewers, film reviwers etc.
What I am saying however, is that quality, being an inherently subjective measure, is in the eye of the beholder. If the majority disagree with an elite minority in a subjective evaluation, that does not make them wrong.
If you want to define quality according to metacritic, then fine, but it will clearly disadvantage Wii and DS, because some of the gaming elite won’t even accept casual titles as games at all.
But to define quality according to sales is equally valid, and more representative. You can’t deny that it is more representative, and it's all subjective after all.
