According to previous GTA 6 speculation, it would primarily take place in Vice City, the series' fictionalized version of Miami. GTA 6 is set not only in Vice City, but also in Liberty City (New York), San Andreas (San Francisco), and Europe, according to industry analyst and insider Michael Pachter. Los Santos (Los Angeles) is not mentioned by Pachter, but it is likely to be included. Pachter mentions that the game will last between 400 and 500 hours.

If that sounds like a lofty goal, it is. If true, that would make GTA 6 the most ambitious game ever made. This, according to Pachter, is the reason why the game takes so long. Pachter says it's been in the works since 2014 and could be released in 2024.

GTA 6 Leak Speculates Game Setting

“GTA 6 has been in development since 2014. They might not be writing code then as they were imagining the story, but in 2015 they were writing code. Anyone naive enough to think that Rockstar and its 2000 employees are sitting on their butts twiddling their thumbs… No they're not, these guys are working hard to create amazing content, but GTA 6 is going to take 10 years or more .

The reason is, from what I understand, it is a mixture of Vice City, San Andreas, Liberty City (so GTA III) and Europe, London for sure. You are going to be able to go anywhere on these continents and you are going to have missions that will take you to all these places.

Pacher continued:

“It will probably be literally a four or five hundred hour game by the time they release it. That's what they're doing now, that's what they turned GTA 6 into. I get it because they're like, we're going to charge you $60 and then we're going to give you an online experience and you're going to have to transport drugs from London to LA, you're going to have to go through the Port of Miami. They're going to do all this really cool stuff.

Pachter is a well-known industry expert who regularly provides a variety of scoops and insider knowledge. However, it is unclear to what extent this is based on reports and to what extent it is pure guesswork. Take everything here with a grain of salt, whatever the case.
