Features of Millennia: Ancient Worlds include:

• Nomadic Band Start: Open the game with an unsettled band of travellers, scavenging for resources to improve the strength of your group until you decide to settle down and form a proper society.
  
  
• New Threats: Megafauna stalk the land, threatening your prehistoric nomads but providing the chance for new events and experiences.
  
  
• New Terrain: A Frozen Terrain start introduces new challenges as it limits resource gathering, but lush grasslands and forests are revealed as the tundra melts and more hospitable settings expand.
  
  
• New National Spirit: Messengers is an Age II National Spirit that emphasises early game diplomacy. Give gifts to your rival nations, gather resources from minor nations and preserve their independence, and reap benefits from the new Llama special good.
  
  
• New Starting Government: Band Society: Rather than building up a Homeland, Band Societies rely on potent short-term bonuses and Tribal Camps to gain an early lead. They also gain a Nomad Band to scavenge terrain and settle an additional Capital Region.
  
  
• New Landmarks: Discover majestic natural wonders as you explore your new world. Mount Jianglang, Iguazu Falls, the Great Redwood Forest and eight more Landmarks can appear on the map, each with its own new Expedition.
