Simple Trans (Expanded)

🏳️‍⚧️ Gender Identity & Reproductive Biology System for RimWorld

A comprehensive continuation of Runaway's original Simple Trans mod, completely rebuilt for RimWorld 1.6+ with extensive medical systems, mod compatibility, and safety features.

About This Version

This is a major expansion of the original Simple Trans mod by Runaway. Originally for RimWorld 1.5, this version has been completely decompiled, modernized, and updated for RimWorld 1.6+ with significant new features and improvements.

Original Author: Runaway
Current Maintainer: azrazalea
RimWorld Version: 1.6+
Original Mod: Simple Trans (RimWorld 1.5)

⚠️ If you're on RimWorld 1.5, please use the original mod!

Core Concept

Separates gender identity from reproductive biology using RimWorld's hediff system. Instead of gender determining fertility, pawns get individual reproductive capabilities and gender identities that can be medically modified.

Trans rights are human rights.

Key Features

🧬 Gender Identity & Reproduction System

• Gender Identity Hediffs: Pawns spawn with "Cisgender" or "Transgender" hediffs (configurable spawn rates)
• Reproductive Capabilities: Separate "Carrying Capability" and "Siring Capability" hediffs control reproduction
• All Combinations Supported: Trans men who can carry, trans women who can sire, etc.
• Fully Configurable: Control spawn percentages and reproductive ability rates
• Updated IVF & Fertility: All surgeries work based on reproductive capabilities, not gender

🔬 Medical Systems

Organ Transplantation

• Extract reproductive organs from one pawn, transplant to another
• Extracted organs maintain their type (natural carrying/siring anatomy)
• Surgery can fail, potentially causing capability-specific sterilization
• Pregnancy safely terminated if carry organs removed (with warning)
• Children from transplanted organs are genetic children of current organ owner

Prosthetic Systems

• Basic Prosthetics: 70% fertility rate compared to natural anatomy
• Bionic Prosthetics: 120% fertility rate with perfect contraception control
  • Both partners with matching bionics wanting children: 100% pregnancy chance
  • Either partner with bionics wanting to avoid pregnancy: 0% chance
• Prosthetics work alongside base capabilities

Sterilization System

• Capability-specific sterilization: "SterilizedCarry" vs "SterilizedSire" hediffs
• Failed surgeries apply appropriate sterilization type
• Backwards compatibility converts vanilla "Sterilized" hediffs

🎭 Ideology DLC Features

(Optional - mod doesn't require Ideology)

Gender Affirmation Party Ritual

• Ritual for changing name and gender identity
• Community celebration of gender transition
• Provides mood bonuses and social recognition

Biosculpter Gender Affirming Cycle

• Body type transformation: Changes physical appearance (vanilla body types)
• Reproductive organ modification: Alters reproductive capabilities
• Removes prosthetics to replace with natural organs
• Cures all sterilizations

🛡️ Safety & Consent System

• Comprehensive informed consent dialogs for irreversible procedures
• Pregnancy preservation warnings with detailed change summaries
• Color-coded UI showing exactly what will happen
• Changes can be undone through additional procedures

🔧 Gene Integration

• Vanilla Expanded Framework: Complete integration with gene systems
• Configurable Gene Behavior: Genes can represent assigned gender at birth OR current identity
• Body Type Respect: Changes respect cisgender status (won't alter cis pawns inappropriately)
• Gene-Gender Conflicts: Handled intelligently

Installation Requirements

Required

• Biotech DLC
• Harmony (brrainz.harmony)
• XML Extensions (imranfish.xmlextensions)
• Vanilla Expanded Framework (OskarPotocki.VanillaFactionsExpanded.Core)

Load Order

Mid-Save Installation

⚠️ If adding mid-save: Go to Development Mode → Debug Tools → Click "Validate All Genders" to set up existing pawns. Use debug tools to customize individual pawns as needed.

Debug Tools

Debug Mode Features

• Extensive logging for pregnancy/romance mechanics and mod compatibility testing
• Enable in mod settings for detailed reports
• Essential for testing compatibility with other mods

Dev Actions

• Validate all genders

• Modify reproductive capabilities
• Clear and regenerate Simple Trans hediffs

Technical Information

Development

This version was created by:

1. Decompiling the original mod using ILSpy
2. Modernizing the codebase with C# best practices
3. Updating for RimWorld 1.6 compatibility
4. Adding comprehensive error handling and documentation
5. Enhancing with improved debugging tools

AI Assistance Disclosure: This continuation makes extensive use of AI coding assistants (Claude Opus/Sonnet 4) for code modernization, documentation, and implementation of new features. The maintainer reviews all AI-generated code, handles complex logic (particularly random pawn generation), and ensures code quality and correctness.

Architecture

• Harmony Patches: Integrates with RimWorld's core systems
• Hediff System: Uses health conditions to track gender identity and reproductive capabilities
• Gene Integration: Works with Biotech genes and VEF extensions
• Settings System: XML Extensions-powered configuration

Building from Source

To compile this mod from source, you'll need:

Original Mod Philosophy (by Runaway):

"This mod was inspired by frustration with other options for having explicitly trans pawns. No shade on RJW, Universal Pregnancy, or Dysphoria, but none of those were what I was looking for here."

Trans rights are human rights.

Support
