Naughty Dog's The Last of Us Online was more than just a "side project," and it's a big reason why the studio hasn't had a brand new game since 2020. According to Jason Schreier, The Last of Us Online was reportedly not a game that was buying the team time until Intergalactic: The Heretic Prophet. It was seen as a major release for the studio, as opposed to a mere side project. Schreier claimed that the majority of the team on Intergalactic actually came over after The Last of Us Online was scrapped.
