PlumAntics Simstrology Mod

Description

PlumAntics Simstrology Mod is the core gameplay package for the Simstrology system.

It gives Sims a Simstrological identity, tracks chart state over time, and powers the shared systems the rest of the Simstrology line builds on.

This is the V2 version of the mod. The biggest change from older builds is that Simstrology now runs on a Python-powered universal Simstrology clock instead of behaving like a collection of separate XML-driven features.

That means the system feels more connected, more dynamic, and more reliable in live gameplay.

What this mod does

Once a Sim is part of the system, the core mod supports:

  • visible Sun, Moon, and Rising identity
  • chart ruler assignment, with interpretation opening at Simstrology Skill Level 4
  • dominant chart element and mode markers
  • natal chart readouts, readable at Simstrology Skill Level 4
  • house systems, readable at Simstrology Skill Level 4
  • progressed Sun systems
  • retrogrades, with notices beginning at Simstrology Skill Level 2 and deeper transit awareness opening at Level 4
  • return-style events such as Moon Return and Solar Return
  • compatibility-style sign discovery and social flavor

The goal is for a Sim’s chart to feel like an ongoing part of their life, not just a one-time assignment.

Onboarding and upgrading

Players can enter the system in multiple ways:

  • Sun First for a more step-by-step route through Sun, Moon, and Rising
  • Rising First for a more snapshot-style route that uses Rising as the anchor

Why V2 matters

V2 gives the mod a shared runtime that can:

  • keep chart timing coherent
  • restore active systems more cleanly on load
  • track chart state more reliably
  • support future add-ons through one live simulation layer

In player terms, the stars are no longer just labels on a trait panel. They are part of an active gameplay engine.

Pairs well with

Best for players who want

  • a core Simstrology framework for the whole save
  • charts that matter beyond initial assignment
  • dynamic systems like retrogrades and chart-based notices
  • a foundation for later skill, aspiration, childhood, and career content
