It features hundreds of autonomous ships using GOAP AI planners to trade, mine, and haul cargo across a living solar economy with emergent market pricing, faction taxation, population migration, and facility degradation. The simulation engine (sim_core) is pure synchronous Rust with no async or IO, embedded directly into the Bevy client so the renderer and simulation share the same ECS world. Currently simulating ~485 agents ticking at p50 10–20ms, with architecture designed to scale toward 100k+ agents. Persistence is handled via SQLite, and the whole thing ships as a single native binary with no runtime dependencies. Released under MIT as an experimental project, the author invites others to fork it, build games on top of it, or extract the economy engine for other uses. ## Full article daily.dev links to this article rather than hosting it.
