The developers behind its virtual Florida share how they built their most ambitious world so far

In 2015, a group of Grand Theft Auto developers from Rockstar North took their first trips to Miami to do field research for the next game in the phenomenally popular crime series. “Before you’re doing hyper-organised research trips, you’re immersing yourself in the place and its history, the vibe of it,” Rob Nelson, one of the lead developers on GTA VI, tells me. “[You see] the physical places you want to move characters through, the experiences you want them to have, and the juxtaposition between the extremes of society that are in Miami.”
