Production is the second half of the economy. After you've built a building, raw resources start turning into something more valuable. Here you'll find out: what can be crafted?, how long does it take? and how do I pick up the result?
Production buildings sit on your captured hexes and transform one resource into another. The basic pattern is always the same:
The idea repeats from building to building: raw → semi-finished → finished product:
Every production building has a production speed and a storage cap.
Open the hex and press the Collect button.
In the same menu press Upgrade. Higher level — more production speed and more capacity.
You can assign slaves or engineers to the building. Slaves work slowly and inefficiently; engineers — the opposite. More engineers — faster product accumulation. Exact settings live in the building's own menu.
