Coins play a big part in most Mario games and New Super Mario Bros. 2 is not an exception. If you collect a total of one million coins, according to Nintendo, you’ll receive something special. We already know that the upcoming game will support downloadable content but there’s more than one reason to connect your Nintendo 3DS to the internet. If you enable SpotPass for the game, every coin you collect will be added to the Worldwide Coin Total, along with other New Super Mario Bros. 2 players. Every single coin you collect will be added to an overall total.
