Content pack

A content pack is an addition to a previously-released "base game." In The Sims series, these packs add new objects and new interactions between Sims, and very often include new neighborhoods, life states, and other features. Content packs cannot be installed or played without first installing the appropriate "base game." Content packs usually follow a theme, with new features, objects, music, and styles tailored to that specific theme. Content packs are known by different names depending on the size of the pack.

Expansion pack
An expansion pack is the most significant content pack available. Expansion packs were introduced with The Sims: Livin' Large and have been a staple of the series, with several expansion packs released for The Sims, The Sims 2, The Sims 3 and The Sims 4. Expansion packs tend to focus on major new features, and many objects, clothes, styles, neighborhoods or worlds, and life states are geared towards the pack's major theme.

Game pack
A game pack is a digital-only add-on pack, introduced with The Sims 4: Outdoor Retreat. Game packs are intended to be smaller than full expansion packs but larger than stuff packs.

Stuff pack
A stuff pack is a smaller add-on pack which typically includes only new objects and clothes for Sims, though some stuff packs do include gameplay changes. Stuff packs originated with The Sims 2, and were released for The Sims 3 as well. Beginning with The Sims 4, stuff packs appear as downloadable content instead of being released on physical discs.

World pack
A world pack is both a digital and a physical add-on pack, introduced with The Sims 3 Riverview, which was the only free world pack. World packs add a new world for The Sims 3 with the addition of new objects, clothes and styles. Each world pack also offers a couple of brand new gameplay objects that are geared towards the pack's major theme. They are a part of The Sims 3 Store and can be also purchased with Simpoints. They are sold separately and as a part of Bundles and Starter Packs.

Free pack
A free pack is just that—a free pack. These are usually smaller than a stuff pack. Only one free pack has been released so far, The Sims 4: Holiday Celebration Pack. The Holiday Celebration Pack was updated with new objects at the same time Patch 27 was released for The Sims 4. They are not to be confused with The Sims 3&apos;s free store objects.

Compilation pack
A Compilation pack is a collection of one or more individual expansion and/or stuff packs. Bundles, starter packs, and deluxe editions are generally all forms of compilations. Compilation packs have been released only for the first 3 games, so far.

Compilations sometimes, but do not always, contain the base game and one or more expansion packs. This bundling can appeal to people who do not yet own the base game, but are interested in acquiring it and one or more expansions. Compilations are often released several years after the initial release of the games which make up the bundle. The compilation is usually priced closer to that of a full expansion pack, where each of the component expansions or stuff packs would have had its price reduced over time. However, compilations can be released concurrently with the release of one of the component games; this is often simply the new expansion pack paired up with the base game, and sold for a higher price than the expansion alone. Compilation packs typically install all the collected packs simultaneously, eliminating the need to install each pack individually.
