I didn't need that site to tell me how good/bad a game was - but it surely helps to prove a point in terms of how well a game was generally received.
The use of averages is a better idea as it will obviously try to sum up what all the rating are but again all of the reviews (Not player reviews) have the same type of agenda which is normally "its highly antisipated so even though it svcks lets give it a 9 or 10" which is shown when compared to other games take Modern Warfare 3 and Battlefield 3 again how did they get the same score when it looks like the Battlefield team worked their asses of and made a great game while Activison gave us the same thing again and gets the same score its simple while it is a good game it is because it is highly antisipated and has a large amount of fans so reviewers are obliged to give it a good review. im sure you have seen a few examples of this. In terms of Skyrim and Dragon Age 2 yes the scores reflect that Skyrim is better and it really is in most respects but a 9.5 after all that is being said here hmm suspicious......
