Biography

A biography, often shortened to bio, is a written story or history about a particular Sim, character, family or household. Biographies for characters appear in The Sims, The Sims 2, and The Sims 3, and family and household biographies appear in The Sims 2 and The Sims 3. Character biographies can be set and edited in Create a Sim or in-game.

Modifying a biography
In The Sims, a player can change a Sim's bio by holding and clicking on the Sim's portrait on the interface. Players can also write a Sim's biography when in Create a Sim. In The Sims 2, a character's biography can be viewed and edited from within the personality panel. A family or household's biography can be changed when the household is selected in the neighborhood screen.

Place within canon
Many pre-made Sims, households and families have written biographies. These biographies allow players to piece together a storyline for that particular Sim or household. These storylines are often intertwined with other Sims and families in the neighborhood or world, creating a broader story for the player to explore.

Biographies play a major part in determining the canon of the The Sims series. Many Sim or family biographies contain information about pre-made characters and families that would not be known simply by looking at the Sim's memories, the family tree, or other sources. However, biographies do not always sync up with one another. Additionally, biographies often portray events or give details about things which cannot happen or do not exist within the game.
