The Sims 2: Nightlife/Attraction and Chemistry

Attraction and Chemistry is a system designed to help build relationships quicker. Knowing how it works can help you choose what sims are more suited towards one another. This page will explain to you how the mechanics of attraction and chemistry works

Attraction
Every sim has a relationship score for each other. They also have an attraction score for each other. Like daily and lifetime relationships, it can be altered. However unlike relationship scores it doesn't start at zero but instead starts at a fixed value that can be altered by these elements: Note that sims don't have attraction for: Attraction can cause lots of things:
 * Personality
 * Zodiac
 * Turn ons
 * Turn off
 * Aspiration
 * Pre-existing relationships
 * Blood relatives
 * Sims of inappropriate age groups
 * 1) It is the only thing that can affect chemistry
 * 2) It affects autonomous behaviour
 * 3) It can unlock socials
 * 4) It can trigger rivalry
 * 5) It contributes to the start of date scores
 * 6) It is required for the Ask...Do You Like What You See?, Flirt... Check Sim Out and Scope Room interactions.

Attraction Score
Below is an overview of how the attraction score works

Personality
Sims attraction score is affected by personality. The more similar the personality is the more attracted they are. There is no way of knowing a sim's personality if they cannot be played. However their zodiac sign can be obtained by the ''Ask... What's Your Sign?'' The following table shows the default personality score by zodiac but will not be completely accurate

Zodiac
Zodiac, like personality, independently contributes to attraction. Unlike personality, it cannot be altered (Personality can be altered through the Encourage... interaction). Each Zodiac sign can either boost, reduce or have no effect on a sim's attraction. The following table shows exactly what zodiac signs are compatible with each other.

Note that because no zodiac favours itself, the only way to achieve maximum attraction is to have personality scores encouraged to similarity. Encouraging personality doesn't change the sim's zodiac sign.

Aspriration
Like personality, if aspiration is similar then there will be high attraction. The next table shows what aspiration favours what.

Turn Ons and Turn Offs
Every sim has two turn ons and one turn off. Turn ons and offs help players decide what sims like about other sims. A turn off has as much strength as two turn ons and can neutralise the effect of those turn ons in the attraction score. There are nineteen different options for Turn Ons and Offs: Turn ons and turn offs can be discovered by asking the other sim what they are. Using this can help you work out what the other sim likes or hates about your sim. You can alter your sim to match other sims turn ons and turn offs with these methods: Alternatively a sims turn Ons and offs can be changed for your sim through either these methods:
