Specifically, EA says:
Maxis has given fans a first look at a very early stage of The Sims’ next generation and creative platform, known by the working title Project Rene. The title “Project Rene” was chosen to evoke words like renewal, renaissance, and rebirth, and to represent the development team’s renewed commitment to the future of The Sims.
The game title stays true to what The Sims has always been about, while also aiming to evolve the way Sims think and behave. This reimagining of The Sims will offer even more ways to play, tools to encourage creativity, and opportunities to tell meaningful stories. With Project Rene, players can play solo or collaborate with others, as well as play their game across multiple supported devices.
The color tool is coming back. There are also different patterns to choose from. Some aspects of the objects can also be adjusted, such as the backrest of the sofa shown.
As with this sofa, individual additional objects can be freely placed on top of larger objects.
In addition, a first look at the object catalog is possible.
Another sequence shows how the game can be played seamlessly on two different platforms (here PC and mobile).
EA also shared this statement:
With Project Rene, players will have the choice to play solo or collaborate with others, and will have the ability to play their game across supported devices.
