Grand Theft Auto 6 will reportedly include life-simulation systems in which diet, exercise, sleep and possibly alcohol affect protagonists Jason and Lucia’s appearance and condition. The feature expands on mechanics seen in Grand Theft Auto: San Andreas and could make the characters feel more responsive to players’ choices.

The information comes from a Dazed feature featuring Rockstar North’s head of development, Rob Nelson, who said the studio aims to allow self-expression while preserving the characters’ identities. Rockstar has also embedded staff in Miami to observe local life for its Vice City-inspired setting, while character switching may let players alternate between Jason and Lucia during activities, such as one driving while the other uses in-game social media.
