What’s New in The Sims 4?

Family Tree Updates!

The Family Tree has been updated to expand how you experience and tell Sims’ family stories. Your Sims now have relationship labels for in-laws, half siblings, great grandparents, and more! Extended family members will also be shown in the family tree. Players can also choose whether adopted Sims are labeled as such in the Family Tree.

New relationship labels include: Mother-in-Law, Father-in-Law, Sister-in-Law, Brother-in-Law, Daughter-in-Law, Son-in-Law, Distant Relative, Distant Relative-In-Law, Half-sister, Half-brother, Stepmother, Stepfather, Stepdaughter, Stepson, Great-grandmother, Great-grandfather, Great-grandson, Great-granddaughter, Parent’s Cousin, Cousin’s Child, Grandniece, Grandnephew, Grand-aunt, Grand-uncle, Ancestor, Descendant, and Relative-In-law. Divorced has a new name: Ex-Spouse, and Deceased Spouse has a new name: Late Spouse.

Close relatives are prohibited from being romantically involved. This prevents autonomous flirting between In-Laws or Step-relatives.

Flared Staircases!

Get ready to create grand looking staircases! Now, you can widen the top or bottom of a staircase (symmetrically or asymmetrically) to give your builds a touch of elegance. Additionally, stair rails can now be applied to only one side of a staircase and we’ve added a slider to change the length of the rail.
