yeah this is actually true and it's sad that there are lots of people that blindly trust review scores. I personally don't even read full reviews anymore because all they do is point out every little flaw in a game, so when i finally play the game I am like expecting to see the flaw that some guy pointed, a flaw that otherwise I wouldn't even notice.
It's better to read users thoughts on the game where they tell you why they enjoyed it, and see if it's something that you think you will like
