Worlds will be split up into different neighborhoods. This means that unlike The Sims 3, the game will not feature an open world. Willow Creek, for example, will contain five different neighborhoods as well as one large park lot. Each neighborhood can hold up to five lots. This may not seem like much, but the public spaces (areas not part of a lot) will have various interactive objects. Even when on a lot, Sims may autonomously interact with objects in a public space, leading to more populated areas outside of lots. As for the lots themselves, you’re free to convert them from residential to community lots and vice versa.
“Counting the number of lots in a single world is a rather arbitrary number in The Sims 4 though, as you can freely travel, move, work, visit, etc, any world, neighborhood, or lot while still retaining the information about who your Sim is, their belongings, their relationships, their family, etc. That’s right, unlike The Sims 3, your Sim can live in one world, and work in another. “You may only have one active lot at a time and will encounter a short load upon traveling between lots, neighborhoods, and worlds. Up to twenty active Sims may appear within your neighborhood at any time within your active lot and the public space. When you travel to a different lot within the same neighborhood, they will remain and continue as they were.
Additionally, the game will feature in-game video capturing via the Cameraman Mode. In this mode you will be able to easily hide the user interface and change the field of vision.
It’s stupid. What is good in open world is that you don’t need to wait till new location loaded.
