What Dhruin says is correct - almost *no* sites really use the 1-10 scale … GamesForWindows mag claims to and does on occasion, but even within a single issue there are clearly more games rated on the '7 to 9 scale' than on the 1-10 scale.
I would really love to hear about all of these sites using the full 1-10 scale.
