The Legend of Zelda: Ocarina of Time set records for sales when it came out and nearly three decades later, its remake is doing the same thing.
Nintendo has issued a corporate release confirming the November 5 release has sold over 5.2m units worldwide in its opening four day weekend, with 810,000 units in Japan and the remainder worldwide. This number instantly would put it as the second best selling Switch 2 game, ahead of Donkey Kong Bananza (5.05m as of September 30) and makes it the fastest selling Switch 2 game to date.
Given its position this holiday, it is highly possible that the Switch 2 release of Ocarina will surpass the lifetime sales of both the original (7.6m) and 3DS re-release (6.44m) by the end of December.
