6 on a scale of 10 is average, not bad.
In my opinion to many games are getting to high of scores to frequently. There's nothing really special about getting 9's or 10's anymore because so many reviewers just had those out.
It's like Kira and Randy from American Idol. They are way to nice, way to often and they vote yes to tons of crap. Where as Simon is the opposite. If he likes you then you know you've got something special.
