An 8.5 is a really good score. GS tends to review games very critically on many aspects most reviewers don't such as doing something new in the game. GS's most critical point against GoW:CoO was that the gameplay seemed recycled from GoW2. Of course, the amount of fun a game gives you is the most important thing obviously. GS is just a very academic review website weighing in more details on a game than most reviewers.
This will only take a moment of your time. *steals your watch*
