Description
Civilization VI is required to play add-on content and some features of the New Frontier Pass require the Civilization VI Expansion Bundle to work.
Includes the Byzantine Empire with Basil II, the Dromon Ship and the Tagma unique units, and the Hippodrome unique district.
- Civ Unique Ability: The “Taxis” ability gives units additional Combat Strength or Religious Strength for each Holy City converted to Byzantium's Religion. Byzantium's Religion spreads when an enemy unit is defeated. Cities with Holy Sites earn bonus Great Prophet points.
- Leader Unique Ability: Basil’s “Porphyrogénnētos” ability allows Heavy and Light Cavalry units to do full damage against cities following the same religion as Byzantium. Basil gains the Tagma unique unit when the Divine Right civic is discovered.
- Unique Units: Byzantium features two unique units.
- The Dromon replaces the Quadrireme, has additional range, and receives additional Combat Strength against units.
- The Tagma replaces the Knight and grants nearby land units additional Combat Strength or Religious Strength.
- Unique District: The Hippodrome replaces the Entertainment Complex district, is cheaper to build, and provides additional Amenities. Grants a Heavy Cavalry unit when the Hippodrome and its buildings are constructed.
Also includes the Gaul civilization with Ambiorix, the Gaesatae unique unit, and the Oppidum unique district.
- Civ Unique Ability: The “Hallstatt Culture” ability allows Mines to provide a minor adjacency bonus for all districts, Culture Bomb unowned territory, and grant additional Culture. Specialty districts cannot be built next to the City Center and do not receive adjacency from other districts.
- Leader Unique Ability: With the “King of the Eburones” ability, Ambiorix’s civilization gains additional Culture based on unit cost when a non-civilian is trained. Melee, anti-cavalry, and ranged units receive bonus Combat Strength for every adjacent combat unit.
- Unique Unit: The Gaesatae replaces the Warrior. It is more expensive to train, but receives additional Combat Strength when fighting stronger units and district defenses.
- Unique District: The Oppidum is cheaper and available earlier than the Industrial Zone and unlocks the Apprenticeship technology when constructed. It is defensible, offering its own ranged attack, and receives a major adjacency bonus from Quarries and strategic resources.
New “Dramatic Ages” Game Mode (Requires the Civilization VI Expansion Bundle to play)
- An optional, specialized game mode with exclusive rule changes:
- A New “Normal”: Civilizations always enter a Dark Age or a Golden Age in every new era, both of which are more potent than ever and eliminate Normal Ages.
- New Policies: Players gain access to special Social Policies instead of making Dedications, including new and updated Golden Policies and Dark Policies that offer more flexibility and power.
- New Golden Age Boosts: Entering a Golden Age with extra Era Score will increase citizens’ Loyalty pressure on nearby civs.
- New Dark Age Challenges: The chaos of Dark Ages can cause cities to rebel!
- New Era Scores: Players gain Era Score by completing Technologies or Civics and promoting units through combat. (Players can still earn Era Score from Historic Moments as well.)
New World Wonders
- Biosphere. Increases Appeal from all Marsh and Rainforest tiles. In the Gathering Storm expansion, it boosts Power and Tourism. In other rulesets, it grants bonus Science for every Marsh, Rainforest, or Woods in the city that built it
- Statue of Zeus. Gives free military units to the city that controls it and increases Production towards anti-cavalry units.
New Map Script
- The Highlands map is a large region dominated by hills and mountain ranges.

Top Sellers Ranking
What this shows: Steam's top sellers ranking is updated hourly based on revenue, not unit sales. A game consistently in the top 20 demonstrates strong commercial performance. Look for sustained periods in high positions (green zones) which indicate stable revenue generation. Sharp drops often correlate with the end of promotional sales or the launch of competing titles. Investors should note that top 10 placements typically have significant impact on quarterly earnings, especially for mid-sized publishers.
Reviews History
What this shows: Review accumulation over time reveals player sentiment and community reception. The line tracks total review count growth—steep increases indicate viral moments or major updates. The colored bars show daily review breakdown: green (positive) vs. red (negative). Watch for sudden red spikes, which often signal controversies, technical issues, or unpopular changes. Sustained green dominance (70%+ positive) correlates with long-term sales success. For investors, review velocity matters—games maintaining 1,000+ reviews per month show healthy engagement. Compare review ratios to Metacritic scores to spot discrepancies between critic and player reception.
Player Statistics
What this shows: Concurrent player counts (CCU) and daily active users reveal real-time engagement with the game. High sustained CCU indicates healthy player retention, which drives ongoing revenue through in-game purchases, DLC, and premium subscriptions. Look for the 24-hour peak—multiplayer games should show clear patterns (evening spikes in major regions). Single-player titles typically see declining CCU over weeks unless major updates or discounts occur. For investors, sustained player counts months after launch signal successful live-service implementation. Sharp drops may indicate server issues, negative publicity, or loss of interest. This data complements revenue estimates—games with 100,000+ daily players usually generate significant recurring income.

Search Interest
What this shows: Google Search trends reveal public awareness and interest over time, independent of Steam metrics. Spikes indicate moments when the game captured mainstream attention—typically around announcements, trailers, beta releases, or launch day. Compare search interest to follower growth to gauge whether marketing efforts are reaching beyond the existing gaming community. For unreleased games, rising search volume suggests effective promotional campaigns. For released games, sustained search interest months after launch indicates lasting cultural relevance. Investors should note: viral search moments don't always translate to sales, but they do indicate brand awareness that could drive future DLC or sequel success. This data helps answer "Is anyone talking about this game outside of core gaming circles?"
