Gamespot is to give MGS4 a 10 rating.

[Impulsivity]

I would never expect anything less then a high 9 score for this game, its amazingly good. Also sponsoring doesn't seem to help game scores, after all Haze sponsored and got a horrid score from both gamespot and IGN for suckage.

Its not fanboyism if the game really is that good, and MGS4 is THAT good. It hasn't gotten a slew of 10s for nothing.
