Map Scale Relative to Prior Titles
According to Rockstar, the full GTA 6 map exceeds Red Dead Redemption 2's playable space by a factor of three and doubles the footprint of GTA 5. Vice City itself is described as twice the size of Los Santos, while the city and its suburbs together reach eleven times the area of Los Santos and its surrounding regions.
Interior Access and World Layering
GTA 6 will feature hundreds of enterable interiors, a marked increase over the handful of homes, shops, and select buildings accessible in GTA 5. The earlier game and its online mode often required loading screens for additional spaces, whereas the extended GTA 6 footage already displayed varied interiors both in and out of missions.
Rockstar's Approach to Open-World Depth
Rob Nelson told IGN that lessons from Red Dead Redemption 2 informed GTA 6's design, aiming for a consistent, densely populated world that draws players into side activities and exploration. He noted the prior title maximized hardware capabilities to create a living environment, and GTA 6 continues that effort to produce the studio's largest and most complex setting to date.
“GTA 6 is a continuation of our team pushing in this direction – doing everything we possibly can to create the largest, deepest, most densely populated and complex world we have ever built for people to get lost in.”
