Our Sims need more depth. Here are things from past games that made Sims more alive and interesting.
1. Personal bios
Many pre-made Sims 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.
2. Favorites (& Dislikes)
Favorites are part of a Sim's personality and can be set for them in Create-A-Sim. There are three types of favorites: food, music, and color. A Sim's autonomous behavior is mildly affected by their favourites. For example, a Sim that likes lobster thermidor will always be very happy after eating lobster thermidor.
3. Zodiac signs
Sims will generally get on well with other Sims who have the same sign, because they are attracted to others with similar personalities. However, personality and zodiac are separate contributors to chemistry, because Sims will keep the same sign even if their personality points are altered. "Attracted to" and "disgusted by" are not absolutes, but modifiers that help or hinder the growth of a relationship.
Sims can discover other people's signs by asking them in the romantic interactions section: "Ask sign".
