I got to ask here same question than in N4G site when this article did come there.
I just wonder why some PS3 owners crying about "biased" reviews, when their favourite game doesn't get perfect 10 in every review? I don't see any "they are so biased" comments under Xbox360 or Wii game reviews even some games get really heavy "punishment" from reviewers.
For example I just love Mass Mass 1 & 2, but same time I can understand if some reviewer will give those games 9 , 8 or even 7 instead of perfect 10. Reviews are always based on personal preferences. Metacritic can give some direction how "good" game is, but in the end it's all about your personal preferences.
It's really strange why some PS3 owners are so eager to say which PS3 game should get perfect 10 and which Xbox 360 or Wii game shouldn't get perfect 10 and whole world should adapt their perspective of what kind of "a good game" should be.
IGN did give GoW3 "only" 9.3 because reviewer did think that too little has chanced since GoW and GoW2, game plot haven't get any better from GoW and Gow2 (and same time Heavy Rain and ME 1&2 has showed that it's possible to tell good stories in games) and it will last only 10 hours if you don't want to collect trophies or play challenges.
For die hard GoW fan game of course is worth of full 10, but why in h*ll call reviewer biased if he thinks that something isn't perfect in GoW3? I can understand that biased rubbish if reviewer would say that game is under all standards and give it 0 points, but 9.3 is VERY GOOD points and he has very valid reasons why he did remove those 0.7 points from perfect 10 in GoW3 review.
