Sinobi posted a list of the top ten third-party games on the Wii in Japan in terms of sales. At the top of the list, based on Enterbrain sales numbers acquired early by Sinobi, sits Capcom's Monster Hunter 3, with 720,000 copies sold.
Despite the best-seller status, we doubt Capcom is pleased with these sales numbers. The publisher famously shipped one million copies of the game, which have yet to sell through. While sales of the hardware bundle have been good, the standalone version of the game sold only 40% of its stock in the first week, and is already being dropped in price in some stores by over half.
