When pre-orders opened, Rockstar called the game a single-player experience. Anyone counting on a GTA Online-style mode on November 19 will not find it in the announcement. What comes after launch is still open.
After the Extended Look, Rockstar also told the press that the game launches without microtransactions and that no generative AI was used to make it. The footage contained no new information about GTA Online.
There is plenty to do alone. The New York Times reported that producer Rob Nelson's playthrough took about 80 hours, covering the main story and optional goals with story consequences.
