VGCharts.org is a decent source when it comes to sales. They don’t use algorithms to come up with a formula that may overestimate or anything like that. They wait for data to come in and add it all up. If anything, they may underestimate sales, which is probably the better scenario.
This time, their data puts New Super Mario Bros.’ numbers at 4.25 million sold, making it the second-best selling Mario game of all-time, behind Super Mario Bros., of course. It also puts it as the sixth-best selling game overall in Japan, though it has a while to go before it makes its way to a significant spot on the worldwide list.
