Take-Two Interactive, the parent company of Red Dead creator Rockstar Games, is duking it out in court with the Pinkerton Detective Agency — yes, they still exist, apparently.

The Pinkerton Detective Agency, who appear in fictional form in Red Dead Redemption 2, issued a cease-and-desist letter to Take-Two, asking for royalties for the use of its name. Take-Two has since fired back with a lawsuit claiming fair use due to the Agency’s prevalence in the historical record during the time period the game takes place.
