The Sims 4 exists in an "alternate universe," separate from the timeline established in The Sims, The Sims 2, and The Sims 3. The alternate universe was created to allow the developers of The Sims 4 more creative control over the Sims and families that appear in the game. It allows well-known and established Sims and families from previous games to appear without disrupting the continuity set by the first three games. Thus, events and Sims which exist in the "backstory" of The Sims 4 can, but do not necessarily, exist within the continuity of the first three games, and vice versa. It could give players a chance to create their own storyline in their own game without the worry of altering the creator's timeline. It is known that The Sims 3 generally took place before The Sims 2, so some Sims would've been dead by the time The Sims 2 started. The Sims 4 alternate universe gave a chance to continue the player's favored Sims' storyline.

Examples of differences between continuitiesEdit

  • In The Sims 2, it is established that Nighat Caliente is the deceased mother of twins Dina and Nina Caliente. The Sims 4 establishes that Katrina Caliente is the mother of the twins. Additionally, unlike Nighat, Katrina is alive at the start of the game.
  • In The Sims 3, Mortimer Goth and Malcolm Landgraab are children, but in The Sims 4, Mortimer is an adult with children of his own and Malcolm is only a teen.
  • The Malcolm Landgraab from The Sims 3 has the good trait whereas the Malcolm Landgraab from The Sims 4 has the evil trait in its place.
