Rockstar would eventually like to create one Grand Theft Auto game with all previous cities from the series. In an interview with Digital Trends, Rockstar North head Leslie Benzies said he envisions players being able to travel back and forth to revisit places they explored in past games.
“Of course at some point we would like to have one big world containing all our cities and let the player fly between them and revisit their favorite areas,” Benzies said. “In that context re-imagining Vice City would be very interesting.”
On the subject of Vice City returning as a future setting, Benzies said “it is always a possibility. There are a few references to the city in our current-gen GTAs so it is part of that HD universe, and it is certainly somewhere we would love to revisit. However Vice City, perhaps more than any other GTA game, was as much about the era as the setting. Miami in the 1980’s is so iconic it would feel strange to revisit the city in a different time period.”
