Economy Under the Hood – Trade & Currency Systems

Oh mighty Tlatoani!

Today we’re diving deep into the economic foundations of Aztecs: The Last Sun, peeling back the layers of how your empire thrives - or falls - through its intricate trade and currency systems. From the humblest cocoa bean to the rare glint of obsidian, every resource has a story and a strategic role to play.





[h3]Cocoa Beans: The Currency of Civilization[/h3]

Cocoa beans serve as the game’s main currency. Collected daily from your residents as taxes (with higher yields from upgraded houses), cocoa is essential for key actions like building Roads, which are vital for worker movement and city layout.

Managing your cocoa reserves carefully is critical, especially as demands grow with city expansion and production needs.

[h3]Obsidian: Rare & Powerful[/h3]

Obsidian is a rare and valuable resource, found in limited locations across the Valley of Mexico. Its primary use is in constructing Blood Beacons, which expand the Blood Zone - unlocking new land for farming, building, and resource collection.

Obsidian can also be purchased through the Marketplace, but it comes at a high price. Use it strategically to fuel expansion at key moments.



[h3]Trade Routes: Expanding Horizons[/h3]

As you explore the Valley of Mexico, you’ll encounter other cities and civilizations. These are not just scenic backdrops - they’re trade partners waiting to be connected.

To trade, you must first complete exploration of a location and construct a Port module, unlocked via technology. Once established, trade routes open up opportunities to acquire:

  • Captives for sacrificial rituals,
  • Raw Food to support your growing population,
  • A variety of materials otherwise inaccessible.




[h3]Marketplace Dynamics: Supply, Demand, Survival[/h3]

Unlocked through research, the Marketplace lets you trade one resource for another - cocoa for wood, stone for planks, and even obsidian (at a steep cost). It’s a great way to stay balanced during shortages.

[h3]Balance is Everything[/h3]

Resources are either raw (from outposts) or refined (from workshops). Both are vital for survival, building, and progression. Resource streams near your city are limited, so expansion and steady trade are crucial.

Keep your economy flowing, use trade smartly, and never run out of cocoa. The survival of your empire depends on it.
