BC4000: Civilization 4X

Begin in 4000 BC with a settler and guide your people from stone tools to the Space Age. BC4000 is a turn-based 4X strategy game where you explore the world, found cities, research technologies, conduct diplomacy, and compete with rival civilizations for supremacy.

Three rulesets in one game:
- Fifth Ruleset: Grow cities through culture and faith, discover natural wonders, and lead your empire into the modern age.
- Second Ruleset: Classic empire building with a vast technology tree, great wonders, diplomacy, and conquest.
- Colonization Ruleset: Sail to the New World, found colonies, trade with Europe and native nations, and fight for independence.

- From Antiquity to AD 2100: Advance through eras, from pre-Bronze Age to Space Age.
- Deep Strategy: Balance growth, science, culture, faith, gold, and military power.
- World Exploration: Scout the map, discover natural wonders, and plan perfect city sites.
