Exactly, Polyhymnia!
The entire world has come to expect games that are rated anything below an 8 to be mediocre, and anything below a 7 to suck. When you score anything less than 70% on a test, you suck, right?
In my game ratings, I primarily rate RPGs. Each game's rating is rated as an RPG. I evaluate on Gameplay, Design, Depth, Story, Effects, and Replay value. Anything below 5 is below 5 for a reason. However, any game that earns a 5-7, in my opinion, is a good game, but just a mediocre RPG! If I give out a 7-8, that means I feel the game is excellent, and one of the better RPGs. RPGs that manage to receive an 8-10, should be considered as excellent games by any standard, and among the top RPG experiences.
Reader ratings for games are WAY too high, simply because people are "afraid" of rating good games as a 5, 6, or even 7. People, please, reserve your 8s and 9s for only the best games, your top 10, for example!

P.S. I just looked at my collection (140 games). Out of my RPG ratings alone, I've rated three 9s, and nine 8s. Most are rated 5-7.
