GTA6 setting year of 2018-2019
Miami-Dade County = Miami/Miami Beach, Coral Gables, Surfside, Bal Harbour , Bal Harbour Islands, North Miami, Miami Shores, Aventura etc.
Broward County = Fort Lauderdale, Hollywood, Pembroke Pines, Pompano Beach, Hillsboro Beach etc.
I also add West Palm Beach area, Orlando, Tampa areas, Atlanta/Marble Hill Georgia area
How it will work ?
Miami and it surrounding areas including Fort Lauderdale, Key west area will be consider South Vice it will be southwestern part of the map of game
in middle of game you will have Orlando and Tampa area to east
Far North area in the game is countryside, Mini version of Atlanta, Hilly areas
GTA6 map will be bigger than GTA5 there should be 3 characters but each area characters will focus on their city, in middle of game 3-5 main players or whatever will meet up in Miami for heist missions or bad a'ss missions.
