I just got a Great Merchant for hitting Economics first. I figure to send him on a trade mission. I am playing on a Pangaea map, and am situated at the east end of the continent. Will I get more Gold from sending him to the far west end of the continent, or by sending him roughly 1/2 way around the world? The west end of the continent is actually closer by square count but that path crosses the "prime meridian" of all qater tiles that all maps have.
