I read OPM (Official Playstation Magazine) Benelux (sold in Holland and Belgium). And they gave MGS4 96% (same score as GTA 4). Only things they didn't like about the game is that it could have been prettier, and the story can be too complex for people who just started playing MGS4.
And before someone says OPM has no credibilty because of haze getting 9/10 in a other PSM, this OPM Magazine gave Haze 65%.
Mkkay enjoy
