To calculate the overall star rating and percentage breakdown by star, we do not use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
My son hasn't played it yet since he got 2 games today. We haven't had any problems with any games or dvds we've bought through Amazon & i personally have bought a lot (new & used). I feel like I'm getting a great deal every time I buy off my Amazon app rather if it directly from Amazon or another company through Amazon. I absolutely love shopping on Amazon.
