About city improvements in Civilization
City improvements are buildings constructed with production shields, each paying gold maintenance every turn. Most affect only their own city — which is why deciding what NOT to build everywhere is the real economic skill.
Strategy — Maintenance compounds: a Temple in every city is fine, a Colosseum in every city will bankrupt an early empire. Build to need, sell what you outgrow.
