The bottom left of the interface holds an action queue where various activities the Sim wants to do are listed. At the bottom are time controls to manage how time passes. There is free camera rotation and various zoom levels to follow the activity from any angle. Sims level up by practicing activities. The game's main currency Simoleons is used to provide for the chosen lifestyle and to buy new items. The build mode has been made easier as items now often click together to form a coherent structure. Entire rooms can be picked up and placed elsewhere and the push-and-pull tool from the character creation mode can be used to alter the walls. The game has two neighbourhoods with ten public venues in total, such as bars, a museum, a park, a gym, and a library.
The Create-a-Style mode has been dropped in favour of predetermined colour sets. The game also no longer employs a seamless open world for different locations, but links together smaller environments with loading screens. All of the terrain has been flattened, without hills, and transportation is no longer present.
