From VGC: “A few days ago, the United States Patent and Trademark Office (USPTO) finally agreed to grant Warner Brothers Interactive Entertainment a patent on its Nemesis system a procedural engine which Monolith Entertainment, a WB Games subsidiary, used to bring the world of Middle Earth to life in 2014s Shadow of Mordor and 2017s Shadow of War.”
