Infinity Ward's Call of Duty: Modern Warfare 2 had a monstrous November, moving more than 6 million copies in the U.S. on the Xbox 360 and PlayStation 3. The retail PC version also contributed, but to a less impressive degree.
According to a new report from Gamasutra on last month's NPD figures, the PC version of Modern Warfare 2 moved "nearly 170,000" copies at retail. That doesn't include figures for Steam, Valve's digital distribution system, which are likely to have been significant—today, over 100,000 Steam users were playing the game online at the same time, but we're not sure how that breaks down to retail and online sales.
Still, at least 170,000 copies to a group of gamers that balked at the lack of dedicated servers and a higher-than normal price tag is.... pretty good?
