1. Call of Duty: Black Ops

Publisher: Activision-Blizzard
Released: Nov. 9, 2010

Last year's smash hit sold 7 million copies in its first 24 hours and hasn't slowed much since the start of the new year. It's the best-selling game of all time in the U.S., and even more impressive: Pre-orders for this year's follow-up are indicating that title—"Modern Warfare 3"—will be even bigger.
