I want to know the answer to the following question:
How many copies of the game had been sold as of March 2011?
All the background I'm provided with is that "The game had sold 5.82 million copies on the Wii as of March 31, 2011[update], and 1.32 million on the GameCube as of March 31, 2007[update].". Is that enough to answer the question?
Answer: yes
