Square Enix announced 5 million copies of Final Fantasy XIII have shipped worldwide. Broken down, 2 million units are in Japan since the game launched in December and 3 million for the West. Keep in mind these numbers aren’t sales figures, just the number of games sent to retailers.
This brings the Final Fantasy series up to 96 million. With Final Fantasy XIV due out later this year, Square Enix has a good chance of passing the 100 million mark.
