The Sims 3 Astrology

Zodiac Sign Compatibility Chart
by Norma Blackburn aka Twinmum from our Forum

The Sims 3 Late Night has introduced astrological star signs for Sims. While the Zodiac does not appear to influence personality, it can impact on relationships between Sims.

Choosing your Sim’s Star Sign
Pre-existing Sims and babies born to your Sims will have a random star sign appointed with no way to change it, but you can select astrological signs for any new Sims you make in Create-A-Sim.

In CAS, there is now an extra tab in the personality section for star signs. When you create a new Sim, they will be assigned one of the Zodiac signs, but you can change this to whatever sign you want. Star signs are not affected by traits (or vice versa) so once you select a sign, it will stay that sign even if you later change the traits of your Sim.

Star Sign Compatibility Chart
Each star sign has six compatible signs. Sims with compatible star signs will find it easier to advance romantically. Don’t worry if your Sims don’t have compatible signs, they can still advance romantically and even marry most times. The game, however, sometimes throws a wrench into the works and makes a pair of star signs somewhat incompatible. These Sims will still have access to all the relevant romantic interactions, but in testing I was not able to marry a pair off – the propose marriage option was there, but more times than not, the Sim who was asked simply broke into laughter before saying no. This incompatibility seems to be random from game to game and is not determined by traits (all my test subjects were identical except for where they fell in the Zodiac).
