Could someone explain what the benefits to Mercantilism are? I do not understand why you would choose that over another civic. 1 free specailist per city is good but you do not get any foreign trade routes. That to me seems as if it would kill your economy.
Thanks for all your input.
For starters, it has good synergy with Representation, Pacifism, Caste System, and the Philosophical trait. If you've got a specialist economy, Merchantilism is very useful.
In addition, as an empire grows, fewer and fewer of your cities end up with foreign trade routes, while foreign civilizations end up with many trade routes to
your cities. IIRC, each civ only gets one trade route to each city in the game. If there's thirty-five cities in the game, and you own five of them, you have thirty potential foreign trade routes. If you own twenty of them, then there's only fifteen potential foreign trade routes. In other words: in a large empire, foreign trade routes favor your rivals, rather than yourself.
Also, foreign trade routes require open border agreements. If you've been conquoring your neighbors, you may not have a lot of people willing to sign one of them with you. Other conditions, where a lack of open border agreements exists, include: isolation , having a different religion from all your neighbors, or having Tokugawa as a neighbor.
All this means that as you move towards a domination victory, a lack of foreign trade routes may become a non-issue.
