Amazon calculates a product's star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.
Good game overall. Great dungeons. Nice visual style. Feels like a Zelda game. Bosses tend to be either annoying or dumb. Delivered promptly by the seller. Online price was fair, but Nintendo shouldn't charge full price for a game that's a remake and is quite short.
