^I linked the info given by another user, who I understand worked in commercial development of games. The difference you're seeing (even counting something around $10 of license to the platform holder) might be in the shipping/media costs?
It might very well be that a $60 game gives a bigger share to the publisher, I merely extrapolated the difference from $40->$50 to $60 - and that's what I meant when I said $4-5 per $10 difference, not intended over the total price.
Of course a bigger share for a $60 game once again doesn't change the gist of the argumentation, but I really can't give you the absolute values with any certainty.
