Short description
A vast 6 handred-square-kilometer world evolves gradually step by step from the wild primitive age all the way to the advanced interstellar age, where countless spaceships are carefully built one after another to boldly explore the boundless outer space.
About this game
Initial Civilization，the Intelligence and resources are the two core attributes of characters, determining whether players can advance to the next era. Progressing to a new era automatically unlocks new crafting methods and technologies. The eras are divided into: Primitive Age, Agricultural Age, Iron Age, Steam Age, Electrical Age, Interstellar Age, and Stellar Age. **Primitive Age**: Players can craft simple survival tools; sufficient wild food must be accumulated to unlock the Agricultural Age. **Agricultural Age**: Crops can be grown for large food supplies; massive iron reserves are required to unlock the Iron Age. **Iron Age**: Players are largely protected from wild beast attacks; substantial iron and sufficient intelligence (gained through thinking, exploration, and interacting with tribe members) are needed to unlock the Steam Age. **Steam Age**: High-strength gear and semi-automatic devices can be crafted; large quantities of iron, copper, oil, and other materials are required to unlock the Electrical Age. **Electrical Age**: Cars, electrical appliances, and electronic products can be made. Rockets can also be crafted, though this is challenging as they consist of hundreds of components. **Interstellar Age**: Unlocked by building a rocket, allowing travel to the Moon, eight planets, and the asteroid belt. Exoplanets harbor abundant and unique resources; additionally, intelligence gained from space exploration increases significantly. **Stellar Age**: Unlocked by mastering nuclear energy and nanomaterials, enabling the construction of sublight-speed spaceships for travel to other star systems. This game functions more like a virtual world, where most objects feature physical simulations. There is no inventory system—characters can only carry items by hand. Even spacecraft movement around planets uses a realistic gravity system: if a ship fails to reach escape velocity (second cosmic velocity), it will orbit Earth indefinitely and cannot travel to other celestial bodies. In space, players can build space stations of any shape, with a maximum size of 600 meters. However, they must monitor the stations’ orbits; a collision with a planet will resu…
