Experience
Experience is the progression resource that makes Home City shipments available. Unlike Food, Wood and Coin, it is not normally spent on units or buildings at the Town Center; it accumulates through actions and crosses thresholds that unlock deliveries from the selected Home City deck.
How it works
Construction, combat, Treasure collection, Trading Posts and other actions can contribute Experience under the relevant game rules. When a threshold is reached, the player chooses an eligible card and sends its shipment; earning the threshold does not automatically pick a card. Shipment eligibility can depend on the current Age and the deck selected before the match.
Player decision
Think of Experience as shipment timing. A Treasure or Trading Post may be valuable both for its direct reward and for bringing the next delivery closer. Select cards around the current bottleneck—workers, units, resources or a structure—and consider whether the shipment arrives in time to affect the next engagement.
Experience as a match resource
Experience, usually abbreviated XP, is the fourth resource used by the Home City system in Age of Empires III. Food, Wood and Coin pay for units, buildings and research; XP accumulates toward the next Home City shipment. When the shipment becomes available, the player chooses one of the cards in the deck and sends its units, resources, buildings or improvements into the match. A card’s value therefore depends on timing as well as its printed contents: an early Villager or resource shipment can accelerate the economy, while a military shipment can defend an age-up or create an attack window. XP is not normally spent on a shipment before the threshold is reached, so every source of experience contributes to the next delivery.
Passive generation and the rising shipment cost
In the standard ruleset, each player receives 2 XP per second, or 120 per minute, before bonuses and map effects. This passive income means the shipment track continues to advance while the player gathers or fights. The threshold rises with each shipment sent, so the opening shipment arrives sooner than later ones. Players should consider the next threshold when deciding whether to delay a card for an ideal moment: a shipment held in reserve does not create additional XP, and spending it promptly begins progress toward the next one. Civilization modifiers alter shipment requirements, meaning the same amount of XP does not produce the same timing for every civilization. The Spanish need less XP than the standard rate, while several civilizations have surcharges.
Building XP bounties
Constructing a building awards a build bounty equal to 20% of its original resource cost, and destroying a building awards twice that amount. These rewards make settlement and siege actions part of the shipment economy. The award is tied to the building’s original cost rather than the value of later repairs, so repeatedly repairing a structure does not create a new bounty. Building placement still needs to serve a strategic purpose: constructing unnecessary Houses or production buildings just for XP can waste resources and builder time. A Trading Post on a Trade Route is especially useful when its route provides experience, since it can add continuing progress as the match develops. Destroying an opponent’s valuable buildings can reward XP while also removing production or map control.
Unit training and combat
Training most military units, Settlers, Villagers, Fishing Boats, Coureur des Bois, Cree Coureur des Bois and Settler Wagons awards XP equal to 10% of their resource cost. Outlaws award 20% of their cost when trained. Killing a unit awards a bounty equal to 10% of its cost, or 20% for outlaws. Unit costs are converted into XP using the game’s resource valuation, so a costly unit can contribute more to the shipment track than a cheap one. These rewards link ordinary army production and combat to Home City support. The player gains value from keeping units alive and finishing enemy units, while losing units gives the opponent a kill bounty. Avoid throwing away expensive units in an unfavorable engagement: the opponent’s XP is only one cost, but the lost army and replacement expense matter more.
Treasure experience
Some map Treasures award XP directly when the Explorer defeats the guardians and claims them. These rewards are separate from the steady trickle and can bring a shipment forward at a useful moment, especially in the Exploration Age. The Japanese Mountain Warrior Home City Card doubles XP earned from Treasures. The Aztec War Chief’s experience aura can increase the reward associated with defeating guardians, but does not multiply the treasure’s own XP. Treasure hunting therefore rewards map control and scouting, but the Explorer should not enter a fight against a stronger guard merely to accelerate a shipment. Compare the reward with the health and time required, then collect the treasure when the army can safely handle the guardians.
Civilization differences
Civilization rules adjust XP requirements and provide different ways to collect experience. The Spanish require 26% less XP for shipments. The Germans require 10% more; Indians 9%; Hausa 8%; Italians 7%; and Maltese 1% more. Japanese shipment requirements increase by 0.1234% for each shipment sent. These modifiers affect the timing of shipments rather than the identity of the card selected, so an opening plan that assumes a universal first-shipment time will be inaccurate. Some civilizations also have specialized XP sources. The United States and Mexicans receive experience books from age advancement and can research additional book-generating technologies. Italians and Maltese can choose the Pope politician for a shipment of 1,000 XP, and Italians have further book sources through politicians. Such rewards can shift a build order by making a shipment available earlier than passive income alone would allow.
Home City cards and trickles
Cards and buildings can raise XP generation or grant books, a crate form of experience. Sumptuary Laws adds 0.15 XP per second to a resource trickle for civilizations that can use it; its complete effect also includes Food, Wood, Coin and Export. European Immigrants provides Settlers and Settler Wagons along with an added 0.45 XP per second, making its economic value extend beyond its immediate units. Other cards improve a building’s XP generation or award a one-time amount. Because a trickle accumulates continuously, sending a card early gives it more time to contribute, while a book shipment offers a larger immediate burst. Choose between these patterns based on how long the match is likely to continue and how soon a specific shipment is needed.
Trade Routes and Japanese wonders
Trade Routes can provide XP when a Trading Post is built on a route set to experience. A route with continuing traffic can make the Trading Post a recurring shipment source, so securing it early may pay off over a long match. The route is contested map control: an opponent can destroy the post or claim a different socket, and the player must weigh the XP setting against Food, Wood or Coin production. The Japanese Torii Gates wonder increases XP from constructing, training and destroying buildings and units, and raises passive experience trickle by 50%. Its bonus makes ordinary economic and military activity feed the shipment track more quickly, so it works best when the player continues to produce and expand rather than waiting at home.
Planning shipment timing
Use XP progress as part of a build order. A player planning an age-up can estimate whether passive generation, a nearby treasure or a Trading Post will unlock a resource shipment before the age completes. That shipment may help pay for the transition, but delaying it also delays progress to the next one. A defensive unit shipment can be timed to meet an attack; sending it too early can leave the force idle, while waiting too long can let the opponent destroy a key building. A Home City card is not the only decision: the arrival building can often be changed to an Outpost or Fort, and naval shipments use their own water flag. Choose the destination that is safe and closest to the unit’s intended task.
Experience across editions
In the original Age of Empires III and its expansions, XP also raised the level of the Home City between games. Higher Home City levels unlocked more cards for future decks, making experience relevant both during a match and across a player’s profile. Definitive Edition removed that progression gate and makes shipments available from the start, so in-game XP still controls the timing of shipments but no longer levels the Home City to unlock cards. This is a major difference when reading older strategy advice: the shipment economy remains central, but advice about grinding Home City levels applies to the original progression system, not the Definitive Edition.
Common mistakes and useful habits
Do not equate experience with a shipment’s resource value. XP is a timing currency: it unlocks a card, but the card’s effect still has to arrive and be used well. Do not chase every treasure when a strong guardian or exposed Explorer risks more than the reward. Build route Trading Posts where they can be defended, and remember that the route’s XP setting competes with other resources. Keep unit production active when it fits the plan, since training and combat contribute XP, but avoid manufacturing units without a purpose. Finally, account for the civilization modifier and any active card or wonder before estimating shipment timing. These habits help explain why a player can send repeated support shipments while another, on the same map and with similar economy, falls behind on Home City deliveries.
Where to spend attention on the XP track
A shipment threshold is a useful planning marker, but it should not dictate every action. An Explorer can collect a nearby XP treasure while scouting a route, and a Trading Post can convert a map socket into long-term progress. Either option has a cost in travel time, defense or resources. The value is highest when it changes a meaningful timing, such as sending a defense before an opponent’s push or receiving an age-up resource shipment as the transition begins. If the threshold is still far away, continue the economic or military plan that makes the shipment useful. Forcing an awkward fight simply to gain a little XP can lose more than it earns.
Reading shipment progress correctly
The shipment counter records progress toward the next card delivery, not a reserve that can be assigned to any future action. Keep the next card’s purpose in mind as XP accumulates: a shipment that arrives after the threatened building has fallen may have little defensive value, while an economic shipment sent during a quiet period can strengthen later production. The rate can change during the match as a Trading Post, Church, card or civilization bonus is added or lost, so timing estimates should be checked again after these changes.
Experience and the Home City shipment queue
Experience advances the Home City shipment queue. As the player gathers resources, trains units, researches technologies and completes map objectives, experience is earned; when the next shipment threshold is reached, a card can be sent from the chosen deck. The delivery may provide resources, units, buildings or an upgrade, and its value depends on when it arrives. A shipment can stabilize an opening, reinforce a timing attack or strengthen an economy, but the deck must be prepared before the match. Track the next shipment while planning: a small action that earns experience may be worthwhile when it brings a key card forward, while a card held for later can align with an age-up.
Sources, thresholds and strategic use
Experience sources and quantities vary by action, civilization, map and game mode. Trading Posts, treasures, unit production, combat and technologies can all affect shipment timing, but not every source is available on every map. Do not assume a fixed number of minutes per shipment: gathering pace, route access, cards and opponent interaction change the result. Use the experience bar to judge whether to contest an objective or save resources for a shipment-supported push. Some civilizations generate or spend experience through unique systems, so their rules should be read on the relevant page rather than generalized to every faction.
