The second entry in Ubisoft's massively successful Just Dance series is the all-time best-selling Wii game not published by Nintendo itself.

That's according to a statement released by Ubisoft Thursday. While exact sales figures were not provided for Just Dance 2, the company did say that the franchise -- which includes both main titles and the spin-off Just Dance Kids, all of them exclusive to the Wii -- has sold 14 million units worldwide to date.

"Ubisoft is incredibly proud of the monumental success Just Dance 2 has had the past nine months," said Ubisoft's North American president Laurent Detoc. "The game’s outstanding performance solidifies the Just Dance brand as a pop culture phenomenon."

While exact figures are not available, most estimates place Sega's Mario & Sonic at the Olympic Games at the former top slot for third-party titles. That series sold 19 million copies worldwide as of April.

The company is set to release Just Dance Summer Party next week on the Wii, and a multi-platform Just Dance 3 -- which includes support for Microsoft's Kinect and Sony's Move controllers -- this October.

Just Dance 2 was the tenth best-selling game in the United States last month, according to the NPD.
