New Super Mario Bros is the first traditional 2D Mario sequel since Super Mario World on the Super Nintendo.
Touted as a return to form for the series, it compiles the best of the 2D Mario games. NSMB has seen across the board rave reviews and having only released in Japan and America thus far, it has totalled more than 2.5 million sales worldwide.
It remains to be seen how much power this classically influenced realisation of the Mario brand has and thus far, things are looking positive.
From a recent Nintendo press release:
“After just 35 days on store shelves, New Super Mario Bros.® for Nintendo DS? has racked up sales in excess of one half million in the United States alone. That's a sell-through rate of more than 20 every minute since the game went on sale May 15.”
