Order of The Sims 2 and The Sims 3 Expansion Packs

Install expansion packs in the order they were released to minimize problems

The Sims is an extremely popular video game series with numerous expansion packs and "stuff" packs. These expansions provided extra features for the originally released versions of the game.

You should install expansion packs in order whenever possible. Each one builds on the previous pack and includes patches for previous expansions as well. Installing them in the order of release limits conflicts and possible errors. For example, a newer pack may contain updates to a previous expansion release, but if that release is not installed at the time, those updates won't be implemented. Subsequently, installing the older expansion then installs an out-of-date version of the feature or function that was updated in the later expansion. 

With that in mind, here is the launch order for the expansions for The Sims 2 and The Sims 3.
