Starcraft II sold a million copies in its first 24 hours on sale. Not bad, but not as great as the last new Blizzard game to be released. How'd it do, then, in its first month on sale?

Better. Blizzard just revealed that the real-time strategy smash has sold over three million copies worldwide since its release last month. For a PC (and Mac!) game in 2010, those numbers aren't good, they're great. Especially when you consider that, like almost every other game Blizzard has ever made, it'll likely still be registering sales ten years from now.
