Wii Party Rocks JapanMichael McWhertor7/15/10 5:40pmFiled to: Sales getThe japanese software chartmedia createSalesSoftwareOnly in Japanwii partyWii28EditPromoteShare to KinjaToggle Conversation toolsGo to permalinkNintendo's newest mini-game good time, Wii Party, makes it debut in Japan, handily defeating its competitors with a strong first week. Does the Wii have a new multi-million-seller on its hands?AdvertisementWith 235,000 copies of Wii Party sold in the first week, it doesn't seem unreasonable for the first-party game to be well on its way to cross the million sold mark. While Super Mario Galaxy 2 may be slowly approaching the million mark after nearly two months on the chart—it debuted with 340,000 in sales during week one—the Wii's more casual-focused games tend to fare a bit better.Wii Party's closest competitor this week was the PlayStation 3 role-playing game White Knight Chronicles II from Level-5. It too is off to a good start. Let's see how it holds up, eh? Other new top ten debuts include Crackdown 2 for the Xbox 360 and Bokujou Monogatari: Futago no Mura for the Nintendo DS. Last week's chart topper, the latest Inazuma Eleven game, slips down to third place, still selling like gangbusters.
