Amazon calculates a product’s star ratings based on a machine learned model instead of a raw data average. The model takes into account factors including the age of a rating, whether the ratings are from verified purchasers, and factors that establish reviewer trustworthiness.
I wish we'd known that games take so very long to download and or update. We bought the discs for a few games, thinking we could wake up Christmas morning and play. Unfortunately, my step daughter was only with us until 4:40 in the evening, so she got to play her new SIMS game for 15 minutes due to the hours it took to download. Other than that we are having fun.
