Civilization 7: Overbuilding, Explained

Civilization 7: A Revolutionary Approach to Overbuilding

Civilization 7 boldly reimagines the classic strategy game by condensing its historical eras into three distinct "Ages," each demanding significant strategic adjustments. This includes a dynamic overbuilding system that's initially confusing but ultimately rewarding.

Switching civilizations and dealing with obsolete infrastructure are key challenges. Mastering overbuilding is crucial for adapting to these changes. Let's break down the two main types of overbuilding:

Minor Overbuilding: Early-Game Adjustments

Throughout the game, you can replace rural improvements (Farms, Pastures, Mines, etc.) with urban buildings. When constructing a new building, you'll see green (unimproved) and yellow-green (improved) tiles. Choosing a yellow-green tile removes the existing improvement.

Why do this? Besides utilizing unused tiles, it allows for "forward-building" (our term). Each worked tile requires a citizen. Replacing a rural tile with an urban one displaces a citizen, prompting you to reassign them, effectively gaining a new worked tile. This is ideal for expanding borders, securing resources, or outmaneuvering rivals.

Major Overbuilding: Age-Based Upgrades

The more significant overbuilding mechanic unlocks at the transition between Ages (Antiquity to Exploration, and Exploration to Modern). "Ageless" buildings (including Wonders) remain permanent. However, many other buildings become obsolete.

Optimal overbuilding usually involves replacing older urban buildings with newer equivalents (e.g., Observatory over Library, Bazaar over Market) to maximize adjacency bonuses.

Strategic Overbuilding Considerations

However, don't blindly follow this rule. Consider the evolving game state. A coastal city might need military upgrades if war looms. Your Legacy Path goals also influence overbuilding decisions. Focus on Treasure Fleets in the Exploration Age and Factories in the Modern Age, regardless of your initial victory path.

Adapting to shifting circumstances is key. A city focused on Science in the Antiquity Age might transition to a cultural focus in the Exploration Age, necessitating overbuilding Libraries with Temples. This dynamic adaptation is a significant departure from previous Civilization games, adding a layer of strategic depth.
