Well, GameSpot seems to have a tendency to give very popular games the worst score of all their peers. IIRC both Halo 3 and Zelda got much lower scores at GameSpot than anywhere else.Show me a gamestop.com ad in a bad game that they gave a very good review, then we can talk.
Out of curiosity what did the Ps3 version get marked down for over the 360 version?You want a real laugh? GameSpot gave the XBox 360 version a 7.0 and the PS3 one a 6.0.
Also, the XBox 360 version has an average ranking of 86.7% (more than one site gave it a 9.0). The PS3 one had an average of 75%.
However, Gamerankings had a lot more 360 reviews on file to sample from.
