Unopened copy of Nintendo's Super Mario 64 from 1996 sells for $1.56 million

An unopened copy of Nintendo's Super Mario 64 has sold at auction for $1.56 million. Heritage Auctions in Dallas said that the 1996 game sold Sunday, breaking its previous record price for the sale of a single video game.

A spokesman did not immediately respond to an inquiry about who purchased the game. Super Mario 64 was the best-selling game on the Nintendo 64 and the first to feature the Mario character in 3D, the auction house said in a statement.
