Although there is no official trailer yet, there are numerous trailers of this game on Youtube. They are probably all fun-made, but some of them look very realistic.
As we can see there are some features that we have been waiting for, such as changing eye, nose, mouth details. Our sim can be transformed into the hero now. The building will never be easier, there is a new wall block system. Terrain editing is finally back.
This really looks too good to be true, but let’s wait a few more months for the official Sims 5 trailer 2023.
