Rockstar Games has revealed more about the scale of the open world in "Grand Theft Auto VI," confirming that Leonida is roughly twice the size of Los Santos and Blaine County combined in "Grand Theft Auto V." It is also the largest game world Rockstar has ever created. Even so, the developers acknowledged that players still won't see every corner of the map by completing the main story alone.

Speaking with Game Informer, Rockstar developer Aaron Garbut said the "GTA 6" map is the studio's largest world yet "by a considerable margin." While the story will naturally guide players through most of its major regions, the team deliberately avoided forcing every location into the main campaign.
Senior Vice President of Narrative Rupert Humphries explained: "Part of the job of the game's story is to bring the player around the map in a way that feels authentic and interesting. We don't have time to take you everywhere, but we want you to be able to explore and get a feel for most of the places, cultures, and vibes."

The developers also stressed the importance of making Leonida's regions feel connected, creating one cohesive world rather than a collection of isolated locations. Vice City is inspired by Miami, while Grassrivers draws from the Everglades. Some of Florida's most famous real-world destinations, including Disney World, Universal Studios, and the Space Coast, home to NASA's Kennedy Space Center, may not appear in the game.
Florida's distinctive climate will come to life through a new advanced weather system featuring hurricanes and powerful winds that can directly affect NPC behavior. More than 170 animal species have also been confirmed, with some featuring rare and legendary variants similar to those in "Red Dead Redemption 2."
