Does a game's platform influence its EDGE score?

TrendAnalyst blog writes: Every time EDGE magazine reviews a Playstation 3 exclusive, they are accused of bias by PS3 supporters, who are then mocked as fanboys who aren't satisfied with anything other than perfect scores for their beloved exclusives. EDGE are known to be harsh graders, and some respect them for using the full 1-10 scale instead of using 7-10 scale like the mainstream gaming press. The counter argument is that EDGE reviews every game harshly and it's pointed out that for every PS3 exclusive that gets low scores like Heavy Rain, there is an equivalent 360 exclusive.

To investigate whether EDGE is just harsh overall, or if it truly judges and scores games based on their platform, blogger TrendAnalyst made a comparison chart of the top 30 games from each platform, as well as the top 30 multiplatform games.
