Yeah, for a NORMAL AAA game it's a big drop off. But Destiny isn't a normal AAA game. It is THE AAA game. Which means tonnes and tonnes of people buy it. People who buy one game a year buy it. People who are super casual and are only going to play the story buy it. That's why there's such a huge drop - because the initial number is so unrealistically high. See? You learn something new every day.
