A full supply chain can feel safe, but it takes building space and careful balancing. I learned that combining my own production with market purchases can be more flexible.

A factory does not need to stop before it becomes weaker. I learned how building age affects efficiency, how that change can spread through a supply chain, and when rebuilding may be worth considering.

The first two factories can make the start of a round feel surprisingly fast. I learned why they finish so quickly—and why choosing them carefully matters later.
