Around hour twenty the stars open up. Research the Space Elevator, build it, and your home world joins a four-planet trade network. Cargo rides the elevator up to a geostationary orbital platform, and freighters fly it out to planets that are genuinely moving. Send a freighter to the Stellar Forge for stellar materials and the Type-1 Energy Matrix. Trade with Asteroid Belt Alpha for uranium ore and quantum crystals. Proxima Colony ships exotic biocarbons. Jupiter Station ships dense matter from the Jovian depths. Click a planet below to see its economy.
Your home world orbits a Class-G star, and the orbits are real: planets and moons actually move, which is where day/night, moon phases, and freighter launch windows come from. None of it is scripted. Three of your trade partners share this system; the fourth, Proxima Colony, sits 4.24 light-years out, so the trade network doesn't stop at Sol's edge. Beyond the home system, a procedural galaxy of star systems waits. Each partner runs its own economy.

Each planet trades different goods. Build the right export and you can pull rare materials home that your factory could never produce on its own.
Your starting planet: a real sphere you walk, sprint, and jetpack across. Earth-analog atmosphere, 12 biomes, full procedural generation. Build your factory here; every interplanetary route originates from your Space Elevator.
An automated megaplatform anchored at the solar corona, operating at the edge of physics. It produces stellar-grade materials in exchange for advanced manufacturing components.
A network of automated mining stations in the asteroid belt. They produce rare minerals in exchange for fabricated components.
A fledgling human colony struggling to establish self-sufficiency. They need raw industrial materials and can offer exotic biocarbons.
A massive orbital platform harvesting Jovian atmospheric gases. They have access to exotic compounds found nowhere else in the system.
Build a Space Elevator and assign freighters to trade routes. Cargo lifts to a geostationary orbital platform, and each freighter completes a full round-trip from there: depart loaded, cross to the partner planet, unload, load their export, return. On the ground, cargo drones cover the same job at planet scale, riding great-circle arcs across the surface.
Travel time varies by route. The Asteroid Belt and the outer colonies are quick runs, while the Stellar Forge at the solar corona is the long haul. Because everything is genuinely orbiting, launch windows fall out of where the planets actually are at that moment. Multiple freighters on the same route stagger automatically so you get continuous throughput.
Interplanetary trade unlocks at Tier 6. Once your home factory is humming, the system is your next playground.
