Can anyone explain how's this, that the lowest mark for RDD - 8 points from Eurogamer is registered only for PS3 version on gamerankings.com?

The same was on metacritic.com, but they've corrected this a day after, while until now Xbox version stands out with a higher rank on gamerankings than it should have!

It's ok if the mark is honest, but the both versions were reviewed together and have got the same mark!!!
