Spacemen, as it is now, is a sand-box 4X game placed in a procedural persistent universe.This means that in the beginning there are no sectors generated in the universe. First time the player attempts to explore one nearby sector, this will be randomly generated if not previously visited. When a new sector is generated, firstly the sun type is randomly decided and based on the sun size and gravity, there are a number of planets added.The planet type is decided based on the distance to the sun. If the planet is in the habitable zone of the sun, the new planet may contain an ocean and may sustain life. The aspect of the planets and resources are decided, again, procedural based on the type (template) of the planet. Of course the sector is persistent, so next time the player visits it, it will be the same. Gravity of the planets and sun, as well as the temperature of the atmosphere (if present) are also calculated procedural.Depending on nearby sectors, the new generated sector can
