After just one week on store shelves, Super Smash Bros. Brawl for Wii has become the fastest-selling video game in Nintendo of America’s history. Since its launch on March 9, the feature-packed fighting action game has sold more than 1.4 million units in the United States, including more than 874,000 on March 9 alone. It has sold at a rate of more than 120 units per minute between launch and March 16.

Super Smash Bros. Brawl features a nearly limitless variety of options for players. Dozens of classic Nintendo characters like Mario and Pikachu are joined by industry icons like Sonic The Hedgehog and Metal Gear’s Solid Snake for all-out four-player battles. The endless customization keeps players coming back for more. The previous game in the series, Super Smash Bros. Melee, became the best-selling Nintendo GameCube game of all time with more than 7 million copies sold worldwide, so it’s no surprise to see this latest installment racking up record numbers.
