Super Mario Odyssey was the best-selling video game of 2017 on Amazon, according to the online retailer. Nintendo also had the second and third best-selling video games on Amazon, with Mario Kart 8 Deluxe and The Legend of Zelda: Breath of the Wild for Switch rounding out the top three.

PlayStation Store credit was the number one (and two) top seller on Amazon, however. Amazon lists the $20 PlayStation Store gift card, which can be used to purchase PlayStation 4, PlayStation 3 and PlayStation Vita games as the number one video game item customers bought in 2017.
