not sure how accurate this is but I was going off of that.
DA:I has sold 6 million. Mass Effect 2 has sold 5 million. And Mass Effect 3 has sold 7 million.
Oh and I'm not doubting you, kanisatha. But can you show me where it's been confirmed that DA:I has sold 10 million? Haven't found anything about that.
BG1 and 2 selling 3.5 millions each is surprising, it seems inflated.
