Egregoria is an open-source 3D city-building game written in Rust with wgpu, inspired by Cities: Skylines but without a grid. It emphasizes socio-economic and logistics simulation, where each citizen has its own thought model so individual actions drive emergent collective behavior.

Use cases

• play an open-source 3D city builder game
• find a free Cities: Skylines alternative
• simulate a city where each citizen makes individual decisions
• watch emergent socio-economic behavior emerge from agent simulation
• contribute to or study a game written in Rust with wgpu rendering
• play a grid-less city building sandbox on desktop

When to choose

• you want an indie, open-source city builder focused on economy, logistics, and individual agent thought models rather than grid placement
• you want to read, modify, or contribute to a Rust/wgpu game codebase under a GPL license
• you enjoy early-stage projects where you can give feedback on Discord or GitHub issues and shape development

When to avoid

• you need polished, feature-complete gameplay comparable to commercial city builders, since the game is still in early development
• you need mod support, which is wanted but has no settled design yet
• you want a casual mobile or browser game, since it is a desktop build requiring the Rust toolchain and Git LFS assets
