(AP) -- U.S. video game retail sales declined 13 percent in January, another down month for the industry after closing out a rough 2009.
In all, Americans spent nearly $1.2 billion on video game systems, software and accessories during the month, market researcher NPD Group said Thursday.
Software sales fell 12 percent from the same month a year earlier, to $597.9 million.
Nintendo's "New Super Mario Bros." was January's best-selling game. "Mass Effect 2" from Electronic Arts was in second place, even though it launched late in the month.
Hardware sales tumbled 21 percent to $353.7 million. The Nintendo Wii sold the most units among the consoles.
