Sims 3: Stuff Packs

In addition to the main expansions available for The Sims 3, there are also smaller expansions called Stuff Packs. While the regular expansions attempt to largely change gameplay or features in some way, the content a Stuff Pack provides is less significant, being mostly a variety of additonal items.

Examples
Movie Stuff: Decor based on differnet movie genres becomes available, including themes like Westerns, superheroes, and horror films.

Fast Lane: Cars are a big deal here, even to the point where Sims can develop a friendship with their vehicle.

70s, 80s, & 90s: Clothing from several decades are offered to players, ranging from bellbottoms and leotards, to skirts and ripped jeans.

Town Life: This pack focuses more on things outside the main Sims house and around the community, allowing players to add content including childrens' recreation and library renovations.
