I can't believe some people are taking this seriously.........
If you replace a couple of games on the ps3 list and a couple on the 360 list with other exclusives then the differences between relative edge scores for the games and the metacritic scores practically vanish. That is how silly this study is, the creator just chooses games to prove a point.
For example if he had replaced the Formula one game on the ps3 list which edge had scored much lower than the metacritic score (40 to 75)with Siren Blood Curse which not only had a higher metacritic score than the Formula One game, but an even higher score from Edge (78 to 80)! (They gave it a higher score than Metacritic) the graph would start to look vastly different. Replace Yakuza 3 with the vastly superior Uncharted 1 which Edge was also nearly spot on the metacritic with and the difference becomes smaller still. Hell, let me pick a few more games I will 'confirm' Edge has a pro PS3 bias lol :)
The moral of the story is that we prefer random samples to cherry picked data for a reason.
