The title sold a million copies worldwide (including online sales we assume), making it the best-selling PC game of 2010 within its first 24 hours of availability. In 48 hours, the long-awaited RTS was purchased 1.5 million times, the fastest of any game in its genre. Additionally, it's reportedly GameStop's quickest-selling PC game since Wrath of the Lich King, the 2008 expansion to Blizzard's World of Warcraft.
That success will continue with analysts expecting six million units to ship by the end of 2010. Before the comparison is made to Modern Warfare 2, which sold 4.7 million copies on day one, it's worth mentioning that StarCraft II is PC-only, and real-time strategies aren't as popular as first person shooters to begin with.
