Are you being disingenuous? Do you really think most reviewers use the whole scoring spectrum?
Yes, there are a lot of people who try to pawn the game review scoring problem off on the expectations of reader instead of the actual reviewers themselves.
Chicken, egg, etc. Reader's expectations were defined by years and years of 7-10 review culture. Don't blame me because a 7/10 for a AAA game means it's absolute garbage, I'm not a game reviewer.
