Kinect sales were strong, launching Kinect Sports into the top 10 for the month.
Elsewhere in the report, NPD says that total new, physical video game sales are down by 9 percent to $5.06 billion, and video game hardware is down a total of 16 percent to $1.84 billion. In fact, the only tracked category that saw year-over-year growth in December was video game accessories -- the PlayStation Move and Kinect pushed that category up 10 percent from last December to sales of $853 million.
Hit the break to see the best-selling titles of December 2010, according to the NPD's numbers. World of Warcraft's Cataclysm expansion makes a solid appearance at No. 3, and Disney Epic Mickey's status as a "core" game on console with a largely casual audience didn't hurt sales too much, apparently -- it came in at No. 6.
