Its not the scale that matters. They don't consider the scale for games like Gears of War 2 for which they happily gave a 9/10. God knows how they gave it that, when it had the most broken online this generation. Maybe they "forgot" to review the online part.
And then you have MGS 4 releasing the same year, with an 8/10. Makes no sense when you compare the scores, unless they "forgot" that MGO is not a part of MGS4 and reviewed them together.
