10) Need for Speed: Hot Pursuit (PS3, 360, Wii, PC- Released 11/16/10)

While the Nintendo DS continued to lead the overall hardware sales rankings--in fact it passed the PS2 on the US' all-times sales charts--the Xbox 360 finished the year strongly with another month atop the home console sales charts. The Xbox 360 had its top-selling month of all time on the heels of Black Ops and the Kinect, becoming the only system to grow in terms of sales in 2010.

In addition to the December sales figures, the NPD also provided a few notes about 2010 sales as a whole. Despite the fact that console and console software sales saw steep drops of 13% and 6%, respectively, the video game industry only saw a slight drop in overall sales, with the year-end figure looking to land between $15.4 to $15.6 billion. The reason? Boosts in the accessories market and PC game sales due to the Kinect and Cataclysm, respectively.

The NPD Group also provided the year-end sales software rankings. Like the new monthly formula, the list ranks the IPs instead of individual games for particular systems. Here's the 2010 sales rankings:
