An unopened copy of Nintendo’s <i>Super Mario 64</i> has sold at auction for $1.56 million. The 1996 game was sold by Heritage Auctions in Dallas, US, on Sunday, breaking the previous record price for the sale of a single video game. A spokesman did not immediately respond to an inquiry from Associated Press about who purchased the game. <i>Super Mario 64</i> was the best-selling game on the Nintendo 64 console, and was the first game to feature the Super Mario character in 3D. The game was also the first to feature a camera that could be controlled by players independent of the character, and popularised the concept of a central hub world. The sale comes just days after an unopened copy of Nintendo’s <i>The Legend of Zelda</i> set a new auction record, selling on Friday for $870,000. Valarie McLeckie, Heritage’s video game specialist, said the auction house was shocked to see a game sell for almost double, two days after the Zelda game broke its past record. In April, the auction house sold an unopened copy of Nintendo’s <i>Super Mario Bros.</i> that was bought in 1986 and forgotten about in a desk drawer for $660,000. Over the past year, the price for video games has been skyrocketing at auction houses around the world. In July 2020, the record price was set for a copy of <i>Super Mario Bros., </i>which sold for $114,000.
