Get ready to feel old. It’s been 10 years and 11 months since the PlayStation 2 launched in Japan. Since then, it’s sold a nearly unbelievable 150 million units worldwide. We’ll probably all be old and gray before we know if the PS3 can match such impressive sales figures, but in the meantime here’s some more PS2 sales trivia: over 10,000 games are available for the system and over 1.5 billion (yes, billion, as in beeeeeellion) pieces of software have been sold for the console. Feel free to start reminiscing about the days of yore, when the PS2 was fresh and new.
