The Sims 2 is a strategic life simulation computer game developed by Maxis and published by Electronic Arts. It is the sequel to the best-selling computer game, The Sims, which debuted on December 14, 2000. Mark Mothersbaugh composed the music for the game.

The Sims 2 essentially revolves around the same concept as its predecessor. Players are free to control their Sims (as they interact with their virtual surroundings) engaging in various mundane activities and forming relationships in a manner similar to real life. Like its predecessor, The Sims does not have a defined final goal; gameplay is open-ended. Sims 2, however, has life goals, wants and fears, the fulfillment of which can produce both positive or negative outcomes. All Sims age, and can live up to eighty-five Sim days depending on the degree of which their aspirations are fulfilled (although one item can extend a Sim's lifespan further).

The Sims 2 builds on its predecessor by allowing Sims, the simulated human characters, to age through six stages of life and incorporating a more powerful 3D graphics engine. It was first released on September 14, 2004 and became an instant success, having sold a then-record one million copies in its first ten days. In addition to its commercial success, The Sims 2 was well received by critics. As of July 26 2007, The Sims 2 has sold more than 13 million units worldwide and is the best-selling PC game of 2004. A sequel, The Sims 3, was announced by EA in November 2006.
