We love Portal 2 and we're happy to see it succeed.
According to Joystiq , Valve boss Gabe Newell confirmed at Games for Change in New York City that his recent award-winner (oh come in, it's guaranteed to win some) has sold over 3 million copies since its April release. He didn't mention platforms but it's likely that he's referring to the total sales across all platforms; PS3, Xbox 360, PC, and Mac. If you're wondering, the first Portal sold 4 million total copies, although that number doesn't count Steam downloads. We always like to see masterpieces in the interactive entertainment realm do well; it proves that there's still a very large audience that appreciates fresh, challenging titles. You've played Portal 2 by now, right?
Now, about Portal 3 …we just hope it won't take too long.
