Sid Meier's Civilization V Walkthrough — Start to Endgame

Sid Meier's Civilization V is the quintessential 4X strategy game where you guide a civilization from 4000 BC to the modern era, competing against AI or human opponents through diplomacy, war, science, and culture. Despite Civilization VI's release, Civ V with its Brave New World and Gods & Kings DLC remains the preferred version for many strategy fans due to its elegant one-unit-per-tile combat, balanced victory conditions, and refined late-game mechanics.

This walkthrough takes you from your first session to endgame content. Each phase has specific goals, priorities, and milestones. Follow this path to avoid common traps that stall most players.

Quick Progression Summary

Phase 1: Getting Started — Capital City

Your capital should be on a river (25% gold bonus) or coast (trade routes) with luxury resources nearby. Hills provide production. High food tiles enable population growth. Never lose your capital — it has the National College and most key buildings.

Level/Difficulty: Entire game Key Rewards: National College, Palace, all national wonders, identity

What to Do in Capital City

1. Learn tech tree. The tech tree spans Ancient Era through Information Era with 80+ technologies. Spend your first session getting comfortable with this.
2. Pick Domination Victory as your starting build. It's the most forgiving option.
3. Rush National College by turn 100 — it gives +50% science in your capital. Build only 4 cities (Tradition) before turn 100 and get Libraries in all of them.
4. Acquire your first equipment upgrade — Giant Death Robot or whatever's available.
5. Clear all main content before moving on.

Phase 1 Checklist

• Understand tech tree fundamentals
• Domination Victory selected and functional
• Capital City main content cleared
• Ready for Border Cities

Phase 2: Early Game — Border Cities

Cities placed to block enemy expansion and control strategic resources. They may not be production powerhouses but deny territory. Citadels (from Great Generals) can steal territory for forward settlements.

Level/Difficulty: Early-mid game expansion Key Rewards: Strategic resources, territory control, military staging

What to Do in Border Cities

1. Work on city-state diplomacy. 30+ independent city-states provide bonuses when allied: Militaristic give free units, Maritime give food, Cultural give culture, Mercantile give unique luxuries, Religious give faith. This system becomes critical from here on.
2. Farm for Giant Death Robot if you haven't already. It's the key upgrade for this phase.
3. 4 cities is optimal for most victories. Tradition social policy tree is designed for 4 cities and National College requires a library in every city.
4. Complete all objectives before pushing to Natural Wonders.
5. Consider whether Science Victory might suit your playstyle better than Domination Victory.

Phase 2 Checklist

• city-state diplomacy integrated into gameplay
• Giant Death Robot acquired
• Border Cities fully cleared
• Ready for Natural Wonders

Phase 3: Mid Game — Natural Wonders

Unique map features (Old Faithful, Rock of Gibraltar, Grand Mesa, etc.) provide powerful tile yields. Finding them gives happiness and can transform a mediocre city into a powerhouse. Spain's unique ability doubles Natural Wonder bonuses.

Level/Difficulty: Early exploration Key Rewards: Massive tile yields, happiness, Spain civilization bonus

What to Do in Natural Wonders

1. Master social policies. Social policies are unlocked with culture points: Tradition (small empires), Liberty (wide empires), Honor (military), Piety (faith), Patronage (city-states), Aesthetics (tourism), Commerce (gold), Rationalism (science), and Ideologies (Freedom/Order/Autocracy). This unlocks a new layer of gameplay.
2. Start working toward Nuclear Missile. It's the best equipment and becomes accessible around now.
3. Trade routes to your own cities boost growth and production. Early game, internal food routes to your capital can double its growth rate.
4. This area is the main skill check. If you can clear it, you're ready for late game.
5. Start investing in great people for the tactical depth you'll need going forward.

Phase 3 Checklist

• social policies mastered
• Nuclear Missile acquired or in progress
• Natural Wonders fully cleared
• Ready for City-States

Phase 4: Late Game — City-States

Independent single-city civilizations that provide bonuses when befriended (60 influence) or allied (above 60). Maritime city-states feed your cities, Militaristic provide free units, Cultural boost policy acquisition. Never conquer city-states unless absolutely necessary.

Level/Difficulty: Entire game Key Rewards: Free food, units, culture, unique luxuries, UN votes

What to Do in City-States

1. Finalize your build. You should be running Science Victory or Domination Victory with optimized gear.
2. Nuclear Missile should be your primary. If you don't have it yet, prioritize getting it.
3. Never declare war without a clear objective — random wars drain resources and create diplomatic penalties. Have a target (enemy capital, strategic resource) before attacking.
4. trade routes optimization starts here. Small improvements compound into massive advantages.
5. Farm this area for the resources needed to push into Strategic Resources.

Phase 4 Checklist

• Build fully optimized
• Nuclear Missile upgraded to max
• City-States fully cleared
• Ready for Strategic Resources

Phase 5: Endgame — Strategic Resources

Iron, Horses, Coal, Oil, Aluminum, and Uranium appear on the map and are needed for specific units and buildings. Controlling strategic resources enables advanced military. Trade deals can acquire resources you don't control.

Level/Difficulty: Era-dependent Key Rewards: Specific unit/building production, trade leverage

What to Do in Strategic Resources

1. Strategic Resources tests everything. Come prepared with your best build and gear.
2. Tradition is the strongest opening policy tree for science/culture victories. Liberty is better for wide empires and early domination. Honor is niche.
3. The endgame loop: run Strategic Resources, optimize gear, push harder content.
4. Experiment with Time Victory for a fresh take once you've mastered the standard builds.
5. This is where trade routes mastery separates good players from great ones.

Phase 5 Checklist

• Endgame content on farm
• Best-in-slot gear acquired
• Strategic Resources fully cleared
• Ready for challenge content

Common Progression Mistakes

• Expanding to 6+ cities early — more cities increase social policy and tech costs. Tradition supports 4 cities optimally. Wide play (Liberty) requires specific strategies to work.
• Building every wonder — wonders take many turns and most aren't critical. Focus on key wonders (National College, Hubble Space Telescope for science; Alhambra, Brandenburg Gate for military).
• Bulbing Great Scientists too early — their science output scales with your current research rate. Using them before Research Labs wastes potential. Save them for the late game.
• Ignoring city-state diplomacy — allied city-states provide free food, units, culture, and UN votes. They're essentially free bonuses for spending gold on influence.
• Leaving cities undefended — even peaceful games require a defensive military. AI civs declare war on militarily weak neighbors. 3-4 ranged units per city is minimum defense.

Key Tips for Smooth Progression

1. Rush National College by turn 100 — it gives +50% science in your capital. Build only 4 cities (Tradition) before turn 100 and get Libraries in all of them.
2. 4 cities is optimal for most victories. Tradition social policy tree is designed for 4 cities and National College requires a library in every city.
3. Trade routes to your own cities boost growth and production. Early game, internal food routes to your capital can double its growth rate.
4. Never declare war without a clear objective — random wars drain resources and create diplomatic penalties. Have a target (enemy capital, strategic resource) before attacking.
5. Tradition is the strongest opening policy tree for science/culture victories. Liberty is better for wide empires and early domination. Honor is niche.
