Now, let's address something that you've been asking for since the release: a timeline or roadmap. I'm thrilled to finally present to you the 2024 Roadmap for Millennia!
![](https://www.eprison.de/pics/games/https://clan.akamai.steamstatic.com/images/44642325/5271ba494afb2c4228b550da8259c72c51d0158c.png)
Now, let me address a few questions before they arise! This is a living Roadmap, we will update it every time we can confirm when and what you will be getting the next update (so, quite frequently!) Consequently, we will likely delve into discussions about Update 3 and offer teasers for Update 4 upon the release of Update 2, and so forth.
Another crucial point I want to emphasize is that while we have two DLCs listed on this Roadmap, you might notice the Nomad Start and Strategic Warfare system under Updates 5 and 6. Why is that? Well, it's because those mechanics are FREE. For those of you who have purchased the premium edition or the expansion pass, rest assured about the value of the DLCs. They contain plenty of content, which we'll share more about later on, but the core mechanics will be FREE and integrated into the base game.
That's enough from me. Let's dive into the changelog for Update 1!
Update 1 Changelog
Featured Changes
- Added a way for players to destroy their Vassals. The option appears when the Vassal is selected and causes some Chaos when used. This cannot be used on Vassals that are the birthplace of a Religion.
- Added new options for the Combat Viewer. In Options, under the Game tab, the “Show Combat Viewer” dropdown presents options for Always, As An Alert, or Never. These change what is shown in the Combat Viewer when you attack. When set to Always (the default), the Combat Viewer continues to operate as it has been. When set to As An Alert, combat will not show the Combat Viewer when you attack, but will cause an alert to appear in the world and on the right (and clicking the alert will jump to the Combat Viewer). When set to Never, neither the Combat Viewer nor an alert is shown when you attack.
- Added a checkbox option for Auto-Skip Combat Animation in the Options menu. When checked, this causes any Combat Viewer combat shown to immediately skip to the end of the combat.
- Reworked the Reinforcements and Forced March Warfare Domain Powers. Previously, Reinforcements would cause a loss of Veterancy and Forced March would cause a loss of HP. Both of these penalties have been removed. In their place, Reinforcements and Forced March now apply a -10% to the Attack and Defense values of all Units in the targeted Army when used. The debuff lasts for two turns and an Army can have one of each (one from using Reinforcements and one from using Forced March). Using either power again while a debuff is already in place refreshes the duration of the debuff.
- Scaling costs are now capped to the maximum inventory amount (400). This means that costs will no longer scale above the typical maximum amount of a resource you could possess. Vassal Integration costs have been similarly capped. This makes a number of things possible, the most obvious being that it removes what was effectively a hard cap on the number of possible Regions.
- Related, we made an overall balance pass on Vassal Integration cost, Culture Upkeep cost, and Unrest suppression (since these are all factors influenced by number of Regions):
It costs a bit more to integrate your first Vassal; increased the cost from 25 to 30 Government XP.
The cost of integrating Vassals increases a bit less with each Region; reduced the scaling of this cost from a 1.5 exponent to 1.4.
Each Region you control costs a bit more Culture; increased the scaling of Cultural Upkeep from a 1.2 exponent to 1.3.
Increased the Unrest suppression of most Capital Buildings that provide Unrest Suppression (also corrected several that had incorrect values):
Watch 5 -> 10
Grand Plaza 10 -> 15
National Resources Office 10-> 20
Emperor’s Palace 3 -> 6
Governor’s Office 2 -> 6
Morality Police 10 -> 20
Public Library 10 -> 20
Military Police 16 -> 25
National Pastime 10 -> 20
Propaganda Studio 4 -> 10
Youth Camp 8 -> 10
Sports Stadium 10 -> 20
Sacred Capital 5 -> 16
Community Center 10 -> 30
Community Housing 4 -> 8
National Security Office 20 -> 30
High Roller Resort and Casino 17 -> 16
Virtual Reality Playground 12 -> 16
The Watch Capital Building no longer has a Region Level requirement.
Decreased the Unrest suppression of most guard Units that provide Unrest Suppression (also corrected several that had incorrect values):
Guard 8 -> 6
Jackal Guard 2 -> 6
Crossbow Guard 12 -> 10
Shogun 15 -> 12
Inquisitor 12 -> 10
Legionnaire 12 -> 10
Reserves 12 -> 10
Elite Shield 12 -> 18
Peacekeeper 24 -> 18
Social Worker 48 -> 20
Balance
PLEASE REMEMBER THAT BALANCE CHANGES WILL ONLY APPLY TO NEW GAMES.
- Adjusted the Opportunist Ideal from Spice Merchants, which allows Merchants and Settlers to convert to one or the other. Increased the cost of converting to a Settler from 15 to 30 Government XP. Increased the cost of converting to a Merchant from 15 to 24 Government XP.
- Changed use of the Opportunist Unit Ability to not scale other Power costs (converting a Merchant to a Settler used to reduce the Spawn Merchant Power cost and increase the Spawn Settler Power cost).
- Local Reforms was providing a 50% Regional Efficiency buff for 5 turns, now provides a 25% buff for 8 turns.
- Increased value of Tapestry Good from 1 Arts XP to 2.
- Completed a pass on buildings unlocked by Innovation Events, upgrading some of their bonuses (the other values provided by these buildings are unchanged):
Gardens of Babylon 1 Art XP bonus changed to 1 Art XP per 10 population in Region.
Colossus of Rhodes 1 Warfare XP bonus changed to 1 Warfare XP per Dock in Region.
Sensoji 1 Arts XP bonus changed to 1 Arts XP per 5 religious Population in Region.
Chichen Itza 1 Diplomacy XP bonus changed to a +1 Diplomacy XP buff to Jewelry Goods.
Machu Picchu 1 Engineering XP bonus changed to 1 Engineering XP per 10 population in Region.
Sistine Chapel 1 Culture bonus changed to a +1 Culture buff on Artwork and Masterpiece Goods.
- Reworked calculations used for Treaty value. Projects, other Treaties, and market purchases are no longer factored in determining the value of a Treaty. Additionally, the amount the larger partner in a Treaty can contribute to the calculation is now capped at 2x the value of the smaller partner. So, for example, if you have 100 Knowledge income and you make a Treaty with a Nation earning 10 Knowledge income, you’ll contribute 20 and they’ll contribute 10 for and average value of 15 Knowledge from the Treaty. Note that this is not the amount you would get in this case, there is still an efficiency factor involved, but it is the most you could possibly get.
- Jackal Guard movement reduced from 30 to 20.
- Jackal Guard adjusted from 19 / 28 to 15 / 23 Attack and Defense.
- Jackal Guard trades 2x attack vs. Cavalry Combat Mod for 1.5x Defense when guarding a City.
- Increased all Leader Unit speeds to match general movement speed of other Units in their era.
- Increased anti-ship line Unit movement speeds (Scorpion Boat 30 -> 50, Nautilus 30 -> 60, Submarine 40 -> 70, Robot Submarine 40 -> 70, Drone Submarine 40 -> 70, Photon Submarine 40 -> 70, AI Submarine 40 -> 70).
- Changed Hydrothermal Generator from providing 4 Power to producing 1 Energy Good.
- Increased Wealth value of Shells from 3 to 6.
- Increased Wealth value of Dye from 6 to 12.
- Increased Collective Farm cost from 53 to 75 IP.
- The Pyramid Temple Improvement can now be worked for 6 Faith.
- Upkeep of Knight increased from 4 to 5.
- Reviewed Improvement upgrade lines based on feedback:
CB Upgrades that didn’t grow over time:
Added Oracle, Baroque Musician, Graffiti Park, and Peace And Love Co-op into a new upgrade line.
Increased Engineering XP in the City Works upgrade line in Age 5 (1 -> 2 XP) and Age 7 (1 -> 3 XP).
Improvement Upgrades that use fewer workers for the same work (and thus less workable by-product XP over time):
Jeweler (1 Gold - 1 Jewelry, 1 worked Arts) upgrades to Jewelry Manufacturer (2 Gold - 2 Jewelry, now 2 worked Arts).
Kiln (1 Clay - 1 Brick, 1 worked Engineering) upgrades to Brickworks (2 Clay - 2 Brick, now 2 Worked XP), upgrades to Concrete Plant (3 Concrete, 3 XP).
Paper Maker (1 Log - 1 Paper, 1 worked Diplomacy) upgrades to Paper Mill (2 Logs - 2 Paper, now 2 XP), upgrades to Paper Factory (3-3, 2 worked XP, extra worker slots).
Saw Pit (3 Log - 3 Lumber, 1 worked Engineering) upgrades to Saw Mill (4-4, 1 XP), upgrades to Lumber Factory (4-4, 2 worked, extra worker slots).
Added Engineering XP to Furnace to make Iron clearly the “Best, but most expensive/longest chain”:
Players that discuss strategy and optimal play were gravitating towards Kilns and Saw Pits and ignoring the “burdensome” iron chain to get their Engineering XP.
Iron “Production” chain is intended to be the “core” production/engineering chain, but doesn’t produce as much Engineering XP as efficiently per-worker as other chains, so we’ve added XP to the Furnace step in the chain to increase Engineering XP.
Furnace (1 Ore - 1 Ingot, 1 Worked Engineering), upgrades to Blast Furnace (2-2, 2 XP), upgrades to Steel Furnace (3-3, 2 XP, extra worker slots), upgrades to Steel Crucible (4-4, 3 XP, extra worker slots).
Overall, these changes are intended to maintain the “XP Per Converted Good” ratios that were falling off as workers became more efficient. This will result in more XP, especially Engineering XP which is affected in multiple places. Engineering XP also tends to be the most valuable in the mid/late game, with the high utility of Clear Cut/Deforestation and Expand Town powers (which were often were taking higher priority than expensive Engineering National Spirit Ideals).
Gameplay
- Made a pass at adjusting some elements of Diplomacy:
Increased the positive diplomatic opinion gained by Diplomatic Actions by 150%.
Rejected Diplomatic requests to establish an Embassy now refund 80% of the cost.
Doubled the rate of Diplomatic Opinion decay (in general, relationship will trend toward a “0” baseline more quickly).
Added or adjusted tooltips and Infopedia details to better explain Diplomacy in general.
- Transports now show the Unit they are transporting.
- Tooltip for Transports now shows health of Unit being transported.
- Unlocking SETI Scan now disables Eureka (as there is no reason not to use SETI Scan and using Eureka was unintentionally making SETI Scan worse).
- Scholars bonus now applies to SETI Scan.
- SETI Scan Event now only happens in Age of Rocketry.

- Previously, there was no benefit to having a landmark in your territory. Landmarks were changed to provide a baseline +1 Culture per turn when within your borders. Beyond the base +1 Culture, Landmarks in your territory provide an additional bonus depending on the Landmark (note that you cannot see what you will get from having a Landmark in your territory yet and the effects are still difficult to see after it is in your territory – it’s on the list):
Mount Everest, Amazon Rainforest, and Congo Rainforest: +1 Exploration
Mount Fuji, Grand Canyon and Aurora: +1 Arts
Borneo Rainforest, Tall Mountain: +2 Production
Yosemite Forest, Frozen Wastes: +1 Government
Sundarbans Delta and Sahara Desert: +1 Diplomacy

AI
- Reworked City, Outpost, and Town placement formulas used by the AI. AI players are better at spacing out their Capital Cities and are less likely to place Capitals or Outposts close to the borders of other Nations if other quality spots are available. At higher difficulties and with the less friendly AI personalities, the AI will still place close to another Nation’s borders.
- AI places higher priority on building the Colony Ship in Age of Departure.
