The major games review sites seem unable to score any game below 7/10 unless it's catastrophically bad (we're talking the gaming equivalent of Manos: The Hands of Fate). But then, those sites are often being paid for advertising the same games they're reviewing, leading to some obvious conflicts of interest.

There wa a case in 2007 where a fairly critical reviewer was fired from Gamespot soon after giving a 6/10 to Kane and Lynch, which Gamespot was also heavily advertising.

And this leads to a situation where fans of a highly-anticipated game can be driven to rage by a review that scores 9.3/10. (Those comments may be a bit tough to navigate, but just start from the last page to go in chronological order and find plenty of wank, preserved in a prisine state since 2008.)
