Big 3 Astrology Mod – v1.3.7

Big 3 is a three-layer personality system, not a zodiac replacement trait.

Each Sim has:
• A Sun trait (identity and values)
• A Moon trait (emotional reactions and mood shifts)
• A Rising trait (social presentation and first impressions)

For example, a Sim with a Virgo Sun, Aries Rising, and Cancer Moon may act decisive and impatient in public, but emotionally retreat and self-soothe when overwhelmed. These internal contradictions are intentional and part of the system’s design.

⭐ Features
• Sun, Moon, and Rising Traits (36 total)

Each sign adds light personality flavor, emotional tendencies, and small behavioral differences that blend naturally with gameplay.

• Automatic Sun Sign Assignment

New Sims are now given a Sun sign based on personality and likes/dislikes. Moon and Rising signs can still be chosen manually through the in-game Simstrology menu.

• Optional Add-Ons

Childhood Astrology and Retrogrades are optional modules that extend the system. They are not required for normal gameplay and do not alter the core Sun/Moon/Rising setup.

• Astrology Skill

Sims can study astrology through books and computers, unlocking themed moodlets and research interactions.

• Computer Features

Discover Big 3 signs, read horoscopes, and access astrology research from any computer.

⭐ What’s New in v1.3.7

Fixed several buff inconsistencies; all mood-related buffs now cycle based on Sun, Moon, Rising, and time of day.

Improved automatic Sun sign assignment for new Sims.

General optimization across the buff engine and sign logic.

Compatibility

Big 3 does not attempt to integrate with other zodiac mods. These mods often operate at different gameplay layers (preferences vs. behavior), and stacking them can produce unpredictable results.

If you wish to switch systems, remove the other zodiac mod and use the Big 3 menu to assign signs.
