Games Like Initial Civilization

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 result in total loss of progress.

Each planet offers an open world of at least 6 handred square kilometers, with dozens of planets in total (the eight planets plus their moons). Exoplanets are far from dull: players must explore a sufficient number of planets and accumulate enough travel distance on each to gain the intelligence required to unlock more advanced technologies. They can also bring Earth’s indigenous people to exoplanets for colonization.

In this world, characters age one year every 10 minutes—meaning players experience a full life cycle every 10 to 10-plus hours, reborn as infants in the civilization each time. If all members of the civilization starve to death or are killed by beasts, players can no longer be reborn, resulting in a game over.

*Initial Civilization* is currently developed by me alone. While many models cannot be perfected, I have tried my best to implement all essential features. Future updates will include team expansion to improve model quality. The Stellar Age is merely the beginning of the game; future updates will introduce the Large Star System Age, Intergalactic Age, Large Intergalactic Age, and Universal Age... The progress of civilization has no end.
