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.
