Evaluation

Primitive Society Simulator has been in Early Access since February 26, 2024, and continues to receive consistent, substantial updates from its solo developer (MagPie at YSH BigDove). The game remains under very active development, with multiple significant updates shipping throughout 2026. Major updates in 2026 include: revised hunger mechanics and animal/plant plague systems (March 3, 2026); an ammunition and off-hand weapon system overhaul (April 19, 2026); a vassal independence tendency and Oracle mechanics system (July 10, 2026, after beta on July 25); and a new expanded map with additional rivers and resources (July 29, 2026). The most recent communication was a bug fix patch on September 7, 2026. The developer has been explicit about upcoming content. The July 10, 2026 post describes the Family System as "a massive system" actively being built toward, noting that previous system changes were "laying the groundwork for this." The July 29, 2026 expanded map update states the map is "designed to accommodate families building estates in the future." The June 3, 2026 post confirmed both the diplomacy-vassal system and the family system are under active development. The developer has also outlined plans for civil official growth systems, ammo levels, commander abilities, and class conflict mechanics — none of which have shipped yet. The studio communicates frequently, candidly, and in technical detail, with no indication of any funding or team issues. The game is clearly well within an ongoing, sustained development cycle with explicit future content commitments.

About this game

Colonies x Grand Strategy

Fusing the intuitive management of Colony-Build games with the clear competitive stakes and vast scale of Grand Strategy.
Dive into diverse breakthrough tactics:
Early Rush • Cultural Expansion • Trade/Slavery • Migration • Enforce other tribes to tribute or become your vassal.
Combine these approaches, restarting to conquer new paths after each victory.

‌Ancient Nations Competition‌
We added simple grand strategy gameplay to colony-building mechanics.
You will lead a branch of ‌Ancient Chinese, starting by building a small tribe: crafting tools, constructing houses, hunting, farming, and raising livestock.
Then face 5 ethnic groups in Asia: ‌Rongdi, Baiyue, Ancient Chinese States, Aryans, Assyrians‌.
From the eastern Yellow River basin to Mesopotamia – rule or be ruled.

‌Tech Tree & Culture Tree‌
Through war, cultural promotion, and migration, increase your influence over other tribes.
Make other tribes submit, pay tribute, and provide you with slaves, armies, and resources.

‌Manage Slaves‌
Gain advanced tools and bronze through technological advantage for trade.
Or prioritize reproduction through ‌fertility worship‌.
Or embrace violence, train professional soldiers, and plunder extensively.

‌Leaders & Grouping‌
Use Leaders to manage groups, reducing repetitive actions.
Set group schedules: labor, create culture, develop tech, or train.

‌Knowledge Inheritance‌
Leaders gain battlefield experience and can be promoted to nobles. Noble ranks unlock unique unit types, attire, and room facilities.


This is the shared morale of a unit. When any member is attacked, in addition to taking damage, it also reduces the unit's overall organization. When a leader's unit reaches 0 organization, the entire unit will rout. You can improve organization by enhancing training, mood, and noble rank. You can also increase organization damage, which is an effective winning strategy besides directly killing enemies.


Construct specialized rooms to meet tribal needs:
Bedrooms, slave quarters, kitchens, meeting halls, granaries, execution grounds, and altars.


Force lifelong labor, OR adopt them into your tribe to bear children.
Execute slaves to suppress rebellions, OR sell them directly.


Tribesmen gain knowledge through labor – lost when they die.
Must carve knowledge onto stone monuments to preserve it.
These monuments become learning tools for future generations.
