StarCraft II continues to be a sales monster one month after the release of Blizzard's long awaited sci-fi RTS sequel. Blizzard has just announced that the game has now sold over 3 million copies worldwide in its first month of release. The game sold over 1 million copies in its first day and over 1.5 million copies in its first 48 hours.

Various financial analysts had previously predicted that the game will sell as many as 6 million copies by the end of Activision Blizzard's fiscal year that ends on March 31, 2011. The game is already halfway to that number and that's doesn't include sales of the game in StarCraft-crazy South Korea where it is still in an open beta stage and in China where the game has yet to be released in any form.
