Content pack

An expansion pack (abbreviated EP) is an addition to a previously-released 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. Expansion packs cannot be installed or played without first installing the appropriate "base game." Expansion packs often follow a theme, with new features, objects, music, and styles tailored to that specific theme.

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.

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 for each of the main series games produced 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.
