Grand Theft Auto 5 copies Take-Two has shipped to date now exceeds 32.5 million. The number comes from the company's fiscal third quarter 2014 earnings report, in which it declared its money-making game the "best-selling video game of 2013," citing data from NPD. By comparison, the publisher also noted the entire NBA 2K series has shipped 35 million units to date.
The number of copies shipped by Take-Two doesn't precisely indicate the number sold to customers, of course. GTA 5 has sold well regardless, earning an estimated $1 billion for the publisher in its first three days at retail. It sold 3.67 million copies at retail in the UK in 2013, leading all games in the region.
