"Sales does not equal quality, but it is still closer to it than any other rating, based on one or a few subjective opinions that might not represent the game's universal appeal."
Sounds like something I said, or like something I said... 
Anyway I like sales because its a non-elitist way of judging a games appeal. Its a good balance to reviews as often-times games are judged too harshly or too easily and its a good counter-balance to that.
Tease.
