Stellar Horizons is a "build your own space program" game where you will lead one of seven Earth Factions to explore and develop our solar system. Designed by a real-life space engineer with a PhD in long-duration spaceflight from MIT, Stellar Horizons is intended to be a plausible representation of the first steps of humanity towards the stars between 2030 and 2169, with each turn representing a year of time. You control your Faction’s space program, outposts, and fleets spanning across the solar system, although you will also have some influence over your Faction’s politics back home on Earth as space development becomes more important.
