Sailing allows you to build Galleys and building two Galleys cuts the time it takes to research Shipbuilding. For example, if you want to build your civilization around naval power, founding a city on the coast reduces the time it takes to research Sailing. Research in Civ 6 is designed to reward focusing on paths through the Research Trees that correspond to your chosen playstyle. The advances that allow these unit combinations can be found in the Civics Tree. Starting in the Renaissance era units of the same kind can combine to form Corps, Armies, Armadas and Fleets. Link a Warrior to your Settler and they'll move together while most Barbarians leave them alone. This can be very useful in the early game when Settlers or Traders are threatened by Barbarians who are smarter than they were in previous versions of Civilization. Combat units can stack, link and defend non-combat units like Traders and Settlers, and support units like Siege Engines and Field Medics. Military Engineers unlock with the Military Engineering advance on the Tech Tree during the Medieval era.Ĭiv 6 reintroduces a limited version of unit stacking.

If you want a road to a non-trading partner or any other location on the map, a Military Engineer can build it for you.

This is a nice way to link your civilization’s cities without having to hassle with plotting a course and guiding a Worker along the route.

Instead, Traders now automatically build a road from their home to their destination city. Unlike Workers, Builders don’t build roads.
