Commercial success sold over 12 million copies establishing Super Mario Galaxy as bestselling Wii exclusive alongside Wii Sports and Mario Kart Wii while earning numerous Game of the Year awards validating Nintendo’s creative risk-taking implementing unconventional gravity-based gameplay within established franchise formula.
