    Show HN: A self-running space economy SIM in Rust and Bevy

    The Space Project is a self-running space economy simulation built in Rust and Bevy. It features Ship AI using a GOAP forward planner for trade, delivery, and exploration, and an economy with order-book markets for 13 commodities. The simulation includes six types of contracts, facilities with production recipes and degradation, factions that manage taxes and subsidies, and populations that consume resources and migrate. Crew members have skill progression and wages, and construction sites materialize new facilities. Persistence is handled via SQLite, and a spatial LOD system optimizes performance.
