Orbis - Tiny Grand Strategy

About the Project

Orbis is a civilization simulation built with a focus on realism and emergence. Instead of scripted events, the goal is to create a living "aquarium" where history emerges from physical causes. You don't just command a state; you influence a complex ecosystem where population, resources, and environment are inextricably linked.

Everything is built from scratch in C++20 and rendered using Vulkan, optimized to simulate thousands of years of history and complex trade networks in real-time.

Key Features (The Simulation)

• Huge map of 163 842 tiles.
• Population as Currency: There is no abstract gold. Every action, from mining to war, depends on your population. Workers are your only true resource.
• Bilateral Barter Economy: A deep resource system where cities trade iron for food or wood for tools based on local supply and demand. No magic global markets, only physical exchange.
• Emergent Technology: Discovery isn't a menu; it's a reaction. Settling near mountains naturally leads to Metallurgy, while coastal tribes master Navigation through activity.
• AI Leader Profiles: States are driven by distinct archetypes (Expansionists, Merchants, Scholars) that react dynamically to droughts, famines, and neighboring threats.
• Dynamic Climate Impact: Milankovitch cycles and seasonal shifts aren't just visual. They dictate harvest yields, water availability, and the survival of your people.
• Data Visualization: Toggle deep analytical layers to track cultural spread, trade flow, soil fertility, and diplomatic friction across the globe.

Current State

This build is a technical alpha focused on the Civilization Simulation. You can observe the rise and fall of empires, the flow of resources, and how geography dictates the fate of nations. I am releasing this now because I believe a great strategy game is first and foremost a simulation that makes sense.

Join the Journey

If you’re interested in emergent systems, grand strategy, or low-level game development, I’d love to have you on the Discord. It’s where I post updates, technical logs, and where you can help me shape the future of the project.
