University and fourth European resource (Probabilities and possibilities)

That’s why I’m not a huge fan of “a new kind of resource” for the sake of having a new kind of resource. XP already abstracts a whole lot of different elements of the period, trade, rare resources, prestige, even technological advancements, and it’s a great design imo. There is no need to break it down again.

That being said, a “new resource” would only be a good design if there are unique ways to spend it in the game.


Yes, capitols come too late in a game and serve no additional purpose.
In vanilla that’s fine, but every new culture group gets a whole lot of “bundled buildings”. Bundled economic buildings can always made fair as Europeans have factories. But it’s not that Europeans can get to imperial age really faster than others so they’ll need a special building to somewhat “delay” their access to imperial techs (even most casual games do not go to imperial)

I think they should follow the US state capitol model, accessible earlier in age 3 and with a few new techs, but a little weaker so that state capitol is still unique enough (it can train building wagons which is already very unique though):

But it could also follow the basilica model that gives unique “shipments”, much like the university in the NE mod.

Besides the XP trickle, I would try to simply make Capitol itself accessible in the Industrial Age, but only Knighthood, Immigrants, and Legendary Native Warriors are accessible in the Industrial Age.


It might just be a rebranding of XP by calling it something else. “Fame” or “Prestige” are just as vague and catch all terms, but are a little more thematic at least.

Xp being called xp is a legacy from aoe3 classic where you leveled up your home cities and earned your cards, no longer relevant.

XP is still XP to gain shipments. And the Homecity level up, and the visual upgrades to the Homecity itself.

It’s only pointless aesthetics now though.

I don’t think it needs a passive effect since that’s just a buff to the European civs only. Maybe a little bonus trickle via aging up with El Presidente could make it a little better but not 100% guaranteed.

One way Capitols could be made a little more relevant could be to give them a pseudo-shipment like the Italian Basilica. This could be a “National Army” that gives the more exclusive units for each civ. Like Consulate Armies, it could give units that aren’t normally trainable.

British - Ships a Rocket and Rangers
Spanish - Ships a Heavy Cannon and Soldados
Dutch - Ships a Heavy Cannon and Blue Guards
Ottomans - Ships a Bombard, Spahi, and Nizams
French - Ships a Heavy cannon and Grenadiers

I 100% agree. None of these techs would be game-breaking to get early or in a revolution. It would even be fine to make it so that revolutions didn’t grant so much population capacity so that Immigrants was actually useful.

Then there is no that problem.
XP trickle as passive effect is the easiest and most decent approach I’ve considered.
Even if 1XP per second is fine.

Italians have their own Capitol too.
And, this greatly affects the balance.
Not like it.

In age 5 a 1XP/s trickle is negligible (shipments would arrive 0.04% faster). Might as well not bother changing it for something like that.

Something impactful like sending armies would make Capitols much more attractive. Age 5 is meant to bring the game to a close, so shipping a big expensive army would help to achieve that. If it costs enough and takes long enough to arrive, it wouldn’t be overpowered.

It happens that before it was a little uneven since a deck of level 40 was always going to be better than a deck of level 10 and that generated that new players did not want to play the game because they were going to be crushed by the most veteran players, now it is a little fairer and it doesn’t change too much that instead of unlocking cards, you unlock cosmetics as always…

I agree. A new resource should be something that isn’t just there. It’s kind of hard to achieve without it being too redundant.

I like that idea.


Hydraulic ram


The cheap and efficient supply of water increases the efficiency of industry, crops and livestock. Water can go against gravity at a great distance from the source of origin.

  • Factories increase production by 5% (also affects speed of heavy artillery).

  • Livestock 5% more productive, since it fattens faster.
    In case of generating wool/milk, the reinvestment of coins is reduced by 10%.

  • Crops 5% more productive.


The Fleming Hydro-Ram is an efficient, lightweight, dependable and inexpensive hydraulic ram pump made possible by modern technology. It works on the same principles of physics that enable its cumbersome predecessors to water the farmlands of Europe, the MidEast and Asia over the past two hundred years.

In 1879, The People’s Cyclopedia included the hydraulic ram among the 55 most important inventions in the history of mankind. It defined the hydraulic ram as: “A simple and conveniently applied mechanism by which the weight of falling water can be made available for raising a portion of itself to a considerable height.”

Analytical Engine

The analytical engine allows you to do math like never before, so you can do research faster.

  • Now the university gains an ability to exchange coins in exchange for a stream of experience. It is similar to real house skills, but you will need coins to activate the skill.

Note: It’s a great invention and that’s why I wanted to propose it here, but I can’t think of a practical use within the game that is original enough. If anyone has a better idea, please tell me.


Analytical Engine , generally considered the first computer, designed and partly built by the English inventor Charles Babbage in the 19th century (he worked on it until his death in 1871). While working on the Difference Engine, a simpler calculating machine commissioned by the British government, Babbage began to imagine ways to improve it. Chiefly he thought about generalizing its operation so that it could perform other kinds of calculations. By the time funding ran out for his Difference Engine in 1833, he had conceived of something far more revolutionary: a general-purpose computing machine called the Analytical Engine.

It could also be implemented on naval trade routes.

Mirror galvanometer

  • Additional improvement to the telegraph network that reduces the maximum experience cost of shipments by -200 XP.

A mirror galvanometer is an ammeter that indicates it has sensed an electric current by deflecting a light beam with a mirror. The beam of light projected on a scale acts as a long massless pointer. In 1826, Johann Christian Poggendorff developed the mirror galvanometer for detecting electric currents. The apparatus is also known as a ##### galvanometer* after the spot of light produced in some models.

Mirror galvanometers were used extensively in scientific instruments before reliable, stable electronic amplifiers were available. The most common uses were as recording equipment for seismometers and submarine cables used for telegraphy.

In modern times, the term mirror galvanometer is also used for devices that move laser beams by rotating a mirror through a galvanometer set-up, often with a servo-like control loop. The name is often abbreviated as galvo.



Agricultural production increases, the more cattle you have.

Poultry farming

Pens spawn a trickle of food, but are limited to build. (They will appear chickens and turkeys in the pens, but it will only be a cosmetic change and will not be interactable).


It’s a pity that this topic has gone quiet. Cool things were created here.

It’s because since they didn’t add any DLC for the game, the game was left in limbo this year…

I also think it’s for not expanding the complexity of the game. Perhaps some of these proposals could be applied within existing buildings as some mentioned above or through cards and alliances with natives.

In my opinion, I would consider making a new game completely inspired by AOE-3 to avoid abrupt and unbalanced changes in the current game. However I think that some of these ideas would not break the game, such as Aquaculture and Forestry.

Yes, maybe they will do it in some future game, like AoE 5 (either in the colonial or modern period)…

Modern period AoE game need a new sub-series (like AoM) becouse AoE 4 is back to medieval age. AoE 5 should be a modern game about Ancient and Dark Age period.
