New Million-Seller! Paper Mario: Sticker Star
Paper Mario: Sticker Star was the final 3DS title to pass the million-sales milestone in 2012, doing so in the final week of the year (ending Dec 29) and becoming the ninth 3DS game to do so overall.
Paper Mario: Sticker Star was released a relatively short time ago, mid-November in North America and early December in Europe and Japan. It reached one million sales after just seven weeks on sale in North America and four weeks in each of the other regions.
Up to this point, each successive Paper Mario title has sold more units than the previous. Sticker Star is the first game in the series released on a handheld console, and it is unclear how this and other factors will affect its lifetime sales so soon after release. However, it seems safe to predict that the game will ultimately sell at least 1.4 million units, enough to outsell the first Paper Mario game for N64.
