With more than 90 million units shipped, Rockstar's Grand Theft Auto V is one of the most successful video games in history from a commercial standpoint. The studio is owned by Take-Two, a publicly traded company whose investors are looking for bigger hits each time out. Can the inevitable Grand Theft Auto VI do even better than its predecessor? That remains to be seen, but one analyst thinks GTA V was the biggest hit Rockstar will ever see.

Rockstar's next big game is Red Dead Redemption 2, which comes out in October for PlayStation 4 and Xbox One. This game will surely be a big success, but Cowen & Company analyst Doug Creutz doesn't think it will sell as well as Grand Theft Auto V.
