1) Pokemon Sun and Moon

7.2 million copies sold in 7 days
Few would doubt any Pokemon game to move significant units, such is the popularity of the franchise, but Sun and Moon rocked the industry with the extent of its success.
Was it merely just the 3-year wait since the previous X and Y games, or was it a marvelous strategy to double down on interest fueled by Pokemon GO fever on smartphone? Regardless, Sun and Moon have gone on to sell over 14 million copies in 3 months, half of which were recorded in just 7 days. That is absolutely bonkers.
Of course, Sun and Moon are two separate games, but even dividing the figure in half still places it above the prior entry on our list.
