10 of the Best Civ 6 Tech Tree Technologies in Civilization 6

The tech tree is what the Civilization game series has always been based on. Researching and unlocking the best technologies is crucial to winning Civilization 6 games. Thrusting ahead in technology can give you decisive economic, strategic, and military advantages over other civilizations. These are some of the best Civ 6 tech tree technologies to unlock in the Civilization 6 game.

Writing

Writing is one of the most essential Civ 6 tech tree technologies because of the Campus district and Library it unlocks. Campus districts are crucial for fuelling scientific research. One Campus District and a Library building alone will give you at least a +4 science boost, more with adjacency bonuses, plus additional great scientist points. So, building Campus districts and their Library buildings is crucial to increasing science research and getting ahead on the tech tree.

Industrialization

Unlocking Industrialization enables you to build Factory buildings, which are one of the most important for boosting production. One Factory gives all your cities within six tiles of it a +3 production boost, which makes it one of the best buildings for increasing production across your civilization. Industrialization reveals coal on the map and gives your mines a +1 production boost. The Ruhr Valley wonder that this technology unlocks is also the best in the game for boosting production within a single city.

Cartography

Cartography is one of the best Civ 6 tech tree technologies because it enables all units to navigate (move) across ocean tiles, allowing for unrestricted map exploration. Unlocking Cartography sooner rather than later is crucial to discovering unclaimed territory on which to peacefully expand your civilization during the early to mid-game. Plus, Cartography also gives Fishing Boat improvements a +2 gold bonus, which can amount to a notable economic boost when you have many coastal cities.

Robotics (Gathering Storm)

Robotics is one of the most crucial Civ 6 tech tree technologies in the Gathering Storm expansion because it unlocks Giant Death Robot. Giant Death Robot is the deadliest military unit in the game, with which you can trample over other civilizations with ease, especially when you unlock it before anyone else. Thus, researching Robotics and adding a few Giant Death Robots to your military is one of the best ways to secure a Domination Victory.

Robotics isn’t so good in vanilla Civilization 6 without the Giant Death Robot. Nevertheless, Robotics is still essential to research for securing space race districts because of the Mars Habitation project it unlocks. Plus, the +1 production bonus for Pastures Robotics gives you can boost productivity for space race projects.

Predictive Systems (Gathering Storm)

Predictive Systems is a Civ 6 tech tree technology exclusive to Gathering Storm that unlocks great unique infrastructure. The Offshore Wind Farm, this technology generates +2 production, +1 gold, and +2 power per a tile. This technology enables you to significantly increase production in coastal cities by adding many Offshore Wind Farms to coastal and lake tiles. That tile improvement is especially useful for boosting space race project production in coastal cities with Spaceport districts during the late game period.

Astrology

Astrology is the most crucial Civ 6 technology for those players seeking a Religious Victory. The Holy Site district and Temple building that this technology unlocks are crucial to generating faith for establishing a religion. Its Stonehenge wonder also grants a free great prophet when built, enabling you to establish a religion all the faster.

Even if you’re not playing for a Religious Victory, researching Astrology is still important for obtaining a pantheon civilization bonus during the early game. Building one Holy Site district and Shrine will usually generate enough faith to establish a pantheon structure for a handy terrain bonus. There are also numerous ways you can turn faith generated from Holy Site districts into a flexible second currency, as covered in this Civilization 6 guide.

Bronze Working

Bronze Working unlocks crucial military infrastructure, resources, and units during the early game, which makes it one of the best Civ 6 tech tree technologies for war mongering. The Encampment district Bronze Working unlocks adds a secondary layer of city defence and enables the building of Barracks that provide a +25% combat experience boost for units. Bronze Working’s Spearman unit is crucial for countering cavalry. The Iron Bronze Working unlocks on the map is also an important strategic resource for recruiting early-game military units like Swordsman, Knight, and Man-At-Arms.

Radio

Researching Radio on the Civ 6 tech tree should be a priority when you’re playing for a cultural victory. Radio unlocks the Broadcast Center, an important building for increasing cultural output and attracting great musicians to your civilization. The Seaside Resort that this technology unlocks is also one of the best tile improvements in the game for boosting tourism and gold, especially for civilizations with many coastal cities. One Seaside Resort can generate anywhere between +4 and +8 tourism and gold for the tile it’s based on.

Flight

Flight is the Civ 6 tech tree technology that enables you to build air units, which are crucial for winning wars in the mid to late game, with the Aerodome district and Airstrip building. However, Flight also provides bonus tourism for all tile improvements that generate culture, such as Colossal Head, Château, Great Wall, Moai, Nubian Pyramid, Open Air Museum, Alcázar, and Seastead. Thus, researching Flight can give your civilization a notable tourism boost if it includes many tile improvements that generate culture.

Stealth

The Stealth Civ 6 tech tree technology unlocks the Jet Bomber, one of the best military units in Civilization 6, alongside the Giant Death Robot. Jet Bombers have fantastic range and are great for wearing down cities, making it much more straightforward to capture settlements with land units. Adding two of three Jet Bombers to your military will give you a decisive air dominance advantage for winning wars in the late game.

Those are 10 of the best Civ 6 tech tree technologies you should research sooner rather than later. Such technologies unlock some of the best buildings, districts, units, and infrastructure enhancements in Civilization 6. Technologies such as Cartography, Industrialization, Robotics, and Flight also have important additional effects for advancing civilizations.
