If 85 is your cutoff, you have missed a lot of great games. I keep my cutoff at 75, usually.
This is still higher than far cry primal, and that sold well, so no, it won't affect sales.
So you mean that even if you're interested in a game and heard good things about it that usually appeal to your general taste, you'll still not give it a chance if it scored lower than 75?
Just asking, as i myself had plenty of fun with games scoring between 60~75.
