November 2010
The first third-party developed Wii game to sell 1 million units is Monster Hunter Tri (Capcom, 2009), which has sol 1.58 million units as of November 2010. Featured in Guinness World Records Gamers Edition 2011

This is significant because the Wii had been available for over 3 years when the game was launched, reinforcing the assertion that it's difficult for third party publishers to shift units on the Wii, which remains primarily dominated by first-party games by Nintendo.
