Ubisoft's Just Dance has sold over 2 million copies worldwide since its release, the publisher has revealed.
The milestone means the game is now the Wii's fastest selling new IP from a third-party publisher to date.
"The consumer response to Just Dance has been overwhelming," said Tony Key, senior VP of sales and marketing at Ubisoft. "With Just Dance's success we've seen a renewal of the music video game genre, as this is truly a game that is accessible and enjoyable for everyone."
Just Dance has been a regular in the UK chart since its release in November. It currently sits at number five in the all-formats chart, and number one in the budget Wii chart.
