The worldwide sales of the Wii version have barely surpassed US sales figures of the PS2 original. However, Capcom expects Okami to still sell steadily because of word of mouth. http://www.nintendoworldreport.com/newsArt.cfm?artid=17236 Christian Svensson, Vice President of Strategic Planning & Business Development for Capcom America, issued a statement regarding sales figures of Okami Wii. According to Svensson, sales of the Wii version of the game are at about 280,000 units worldwide while the PS2 version moved about 275,000 units in America alone.
Many publications have mistakenly reported that Okami Wii has finally surpassed sales of its PS2 counterpart, hence the comments from Svensson. Though Svensson did suggest that Okami Wii "was never predicated on reaching the sales of the PS2, so from a profitability standpoint, [Capcom is] relatively pleased with where it’s at and where it’s going."
Though Okami has not seen widespread retail success, Svensson reports that there is "slow, steady business" with the game, proving its staying power in the retail space. Svensson went on to say that he believes the "legs" Okami is exhibiting "is due to word of mouth from fans like all of you," and he urges players to "recommend it" if they "think it’s something [their] friends should be playing"
