Zodiac sign

When creating a new Sim in The Sims and The Sims 2, the Sim will be given the Zodiac sign that's closest to the personality you chose. In The Sims 2, you also have the opportunity to select a sign from the Zodiac, and use the preset traits for that sign. Personality traits affect not only the things Sims prefer to do, but also their relationships. In The Sims 3 this was replaced by a Traits system.

Sims will generally get on well with other Sims who have the same sign. "Attracted to" and "disgusted by" are not absolutes, but modifiers that help or hinder the growth of a relationship. Sims with incompatible signs can become good friends, and even lovers, if they have enough else in common. However, it'll take longer, and they'll have to work at it harder. Likewise, Sims with compatible signs but little else in common will have trouble building a relationship, and may even end up becoming enemies. The compatibility among Sims involving the zodiac is very different from real life. In the chart above, it shows that a sign from column 1 is compatible with a few signs that it is not normally compatible with. They are sorted by an element, and within the following groupings, these signs are best compatible::

Air: Aquarius, Gemini, Libra

Fire: Leo, Sagittarius, Aries

Earth: Virgo, Capricorn, Taurus

Water: Pisces, Cancer, Scorpio
