the average score consists of two people >.>
2 weeks ago our user score of Duke Nukem Forever (Xbox 360) was as high as 8.3 (maybe even more) and had over 10 people rating it. That still DOESN'T mean it's a great game.
I've played it, but I thought it was so bad that I sold it again, thus I'm not adding it to my collection and give it a bad score.
