There's plenty of great games out there scored low by reviewers. Most of them on Nintendo systems.
I can remember my first experience thinking a game was getting obvious downscores was Fire Emblem: Sacred Stones back on the GBA. It was getting avg scores of 8.5 from most sites, for a game that had obvious improvements over its predecessor (which scored higher on nearly all sites). And many similar examples of 'down scoring' to GBA titles followed.
This was also the period when I stopped reading reviews. It was obvious then what a lot of people are learning now. Reviewers were developing an 'anti-Nintendo' bais. It didn't start with the introduction of the Wii or even the DS. It began back with the GameCube and the GBA and even possibly before that.
