Content pack

Expansion packs (EP) are add-ons for The Sims games. They make the original game more interesting by providing new things to the game, and are often centered around a theme. They require the original game (also known as base game or core game) to work. Sometimes, collections or compilations of the base game and one or more expansion(s) are released. The Sims 2 and The Sims 3 also offered mini-expansions called stuff packs (SP), which offered only new objects and clothes, though they sometimes included gameplay changes as well. Gamers are advised to check what an edition includes before buying it.
