Castle role
Castles provide strong defense, train many civilization-specific units, and unlock important research. Their high cost and construction time make placement a major decision for protecting resources or controlling contested ground.
Overview
Castles provide strong defense, train many civilization-specific units, and unlock important research. Their high cost and construction time make placement a major decision for protecting resources or controlling contested ground.
How this system affects decisions
Economic systems are shaped by worker travel, access to safe resource sites, and the time spent gathering versus building or moving. Compare a change by how many workers it affects and how long it remains useful, then balance it against the food, wood, gold, and population required to keep the army active.
How to use this reference
Castles provide strong defense, train many civilization-specific units, and unlock important research. Their high cost and construction time make placement a major decision for protecting resources or controlling contested ground. This mechanic links settlement layout to defense. Keep access routes open for your own units, and consider how the structure’s footprint or interaction changes the time an opponent needs to reach workers.
