The main missions of Grand Theft Auto VI reportedly will not take players across the entire map, and relying solely on story missions may not allow access to all key areas. This claim comes from a media-reported post on X, attributed to Rupert Humphries, who is said to be involved in the game's narrative work.
According to the report, the development team did not have enough main story time to take players to every location, but they hope players will explore on their own to get a sense of most locations, cultures, and atmospheres in the game. Therefore, completing the storyline does not mean you have seen the entire map.
Some areas of Leonida State may be covered by side quests, random events, collectibles, or free exploration. These are descriptions of gameplay arrangements and do not confirm that all content has been officially verified.
There are also rumors that the main story of Grand Theft Auto VI lasts about 80 hours. This duration has not been independently confirmed.
