The Sims is a strategic, life simulation video game series developed by Maxis and later by The Sims Studio, and published by Electronic Arts. It is one of the most successful video games series of all time. As of May 2011, the franchise has sold more than 150 million copies worldwide, and is also the best-selling PC franchise in PC history.
The games in The Sims series are more of a sandbox game in that they lack any defined goals (except for some later expansion packs which introduced this gameplay style). The player creates virtual people called "Sims" and places them in houses and helps direct their moods and satisfy their desires. Players can either place their Sims in pre-constructed homes or build them themselves. Each successive expansion pack and game in the series augmented what the player could do with their Sims.
