- Main article: Trade Route (Civ6)
The Trader functions much like the Trade Convoy from Civilization: Beyond Earth: Rising Tide. It is able to establish a single Trade Route over land or water (after researching Celestial Navigation) to any city in range, whether from your own empire or a foreign one.
Land route range is 15 tiles while sea route range is 30 tiles. These ranges, however, may be extended by establishing Trading Posts in cities. Afterwards, passing through any city with a Trading Post refreshes the range of the unit, effectively doubling it.
In the later eras, the land sprite for Traders changes from a cart to a cargo truck.
As soon as there were villages, there were traders. At first they used poor, dumb brutes – horses, mules, camels, llamas, men – as beasts of burden to carry gems, precious metals, spices and anything else that would turn a profit in a distant village. Every civilized, and many not, land was crisscrossed with trade routes, and these routes – such as the great Silk Road from China to the Middle East – shaped boundaries and civilization as surely as did any war or religion. In time, some traders took to the seas; many of the earliest written records are inventories of commercial goods in ships’ holds, and archaeology shows evidence of sea-going cargo ships in the Mediterranean and Red seas by the beginning of the first millennium BC. As longer voyages of trade were undertaken, cargo ship design was constantly revised; and the beasts of burden were replaced by truck convoys. But the same principle drives trade still … the human need to make a profit.
