Open Almond Core System

Integrity Engine

A story-driven tabletop RPG framework for conviction, pressure, and endurance.

At its center is one question: who are you when the pressure increases?

System Overview

A framework built for who characters become under pressure.

The Integrity Engine is a tabletop roleplaying system built around character conviction, moral pressure, and endurance through hardship. It is designed for stories where choices carry weight and identity is tested over time.

Many systems center power escalation, combat optimization, or resource loops. The Integrity Engine instead centers conviction, consequences, community, and the cost of standing firm.

It exists for groups who want stories about moral courage, identity, and perseverance under strain, with structures that support meaningful decisions instead of just tactical escalation.

Why It Feels Different

  • Conviction and identity are central, not just combat efficiency.
  • Moral pressure and meaningful consequences are core play, not side flavor.
  • Endurance, loyalty, and community matter as much as individual capability.
  • The engine rewards meaningful decisions over optimization loops.
  • Campaigns focus on who characters become when pressure increases.
