Take Two says GTA Online was the single largest driver of recurrent consumer spending during the past quarter.
It's confirmed GTA Online will have more content updates. The game has now sold in over 90 million units worldwide!
For reference, this means that the game sold in 15 million units in the past year. This is 15 million units in 2017 for a game that came out in 2013.
This means it outsold most games that launched in 2017, such as Battlefront II which sold in 7 million units in the year.
