To calculate the overall star rating and percentage breakdown by star, we don’t 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.
I've played this on 3 platforms now. Finished on PS3, then PC, now on PS4Pro. Also played a fair whack of online as well on PS3. An incredible achievement at the time, and still feels like that to this day, only to be surpassed and made to look dated by RDR2.
