World
- For the "open world" neighborhoods of The Sims 3, see Neighborhood#The Sims 3.
In The Sims 4, a world is a collection of individual neighborhoods (also known as districts) within a single playable map.
Two worlds have been confirmed for The Sims 4 so far. The first is Willow Creek[1]; Willow Creek consists of five neighborhoods[2]. The second world is desert-themed, but its name and the number of neighborhoods or lots it has is not known yet[3].
Travel between neighborhoods is possible, as long as both neighborhoods are within the same world. Travel within a neighborhood is still "open" as in The Sims 3, but Sims outside the loaded neighborhood cannot be directly controlled. Players can switch between neighborhoods at will, though this brings up a loading screen[2]. Sims can freely travel between different worlds[4].
