Sovereign Empires runs on a stock-and-flow economy of thirteen resources. Each empire holds a stock of every resource and earns a per-tick flow from its cities and districts. Run a flow negative for too long and the stock drains — economy is a constraint you actively manage, not a number that only goes up.
Resource types
Resources fall into a few broad roles:
- Currency — Gold, the universal medium for upkeep and trade.
- Food — sustains population and unit upkeep.
- Raw materials — Wood, Stone, and ore-line inputs harvested from the map.
- Refined materials — produced by districts that consume raws.
The full list spans thirteen resources; specialized districts let you bias hard toward any one of them.
Finite map nodes
The most important rule: map-tied raw nodes are finite. Forest, Rock, and Ore nodes are placed on the world map and deplete as you harvest them.
That single mechanic drives the whole strategic loop:
| Behavior | Consequence |
|---|---|
| Over-harvest one region | Nodes run dry; output collapses |
| Expand to fresh territory | New nodes, but exposed borders |
| Specialize districts | Higher output, narrower economy |
Cities vs. districts
A city yields a generalist baseline across resources — enough to keep an empire alive. A specialized district, laid out on a claimed tile’s 32×32 grid, optimizes a single resource far past what a generalist city produces.
The trade-off: districts cost build-out and tie you to the geography you settled. Where you expand decides what you can produce; how you lay out each district decides what you do produce.
