@ Mercantilism vs. Free Market, trade route yield
Hmm, maybe if you have just foreign routes which yield one or two commerce.
But if the yield is 5 (maybe you can also add harbour to get even more) I would prefer the route.And probably there is not only a single foreign route per city.
Representation and wonders might chance the picture though.Heroes question hits the point, I think - it mainly depends on how big the route yield is.I have no exact formula, but it depends on the overall wealth of the city.So if you are among the ones, who like to build many and early cottages, the routes are likely better.
If you have few cottages and other commerce sources (which means that you are usually rather not in a leading position), Mercantilism might be good idea to catch up.Specialists can produce whatever you need (production, culture, money, research) and the AI often goes for you, if you are weak.So OBs and foreign trade routes might be no more big deal.
I will add this aspect, too.
A key point of mercantillism is that it's great partner with representation. Every city gets a free 6 beaker scientist of 2 hammer + 3 beaker engineer. If you manage to get statue of liberty, then mercantillism + representation works even better.
So if any other market civic would compete mercantillism, it should generate or save sth. equivalent to 6 beaker per city, by itself or by combination with some other civic. State property could be better than mercantillism, partly for +1 food to watermill and workshop, so you can get the specialist back, though using a true citizen.
How is free market? I just finish a war in 1530 AD as police state + vassalage + caste system + mercantillism + organized religion, so I try several possible revolutions. Under mercantillism, every city has 2 trade route, each worth 1-2 gold, certainly not great. Change to free market, 1 city gets 3 +7 trade routes. However, most cities still run +1 or +2 trade routes. Even though corporation (after 1 turn) will add 1 trade route in every city, it still ooks not quite profitable overall.
Before revolution, 50% science with -34 gpt, F2 shows 373 beaker per turn, 460 gold revenue, civic cost 169, inflation 31% is 121, total expense 514.
Revolt to universal suffrage (well, is there any better combination for free market?) + free market: 50% sicence with +30 gpt, 388 beaker, 489 revenue, 142 civic, 479 expense.
If keep mercantillism and revolt to representation + free speech: 50% with +56 gpt, 488 (!) beaker, 490 revenue, 104 civic, 454 expense. This is the best civic I can get from 1 turn revolution in term of research.
OTOH, if revolt to universal suffrage + free speech: 50% with +27 gpt, 392 beaker, 478 revenue, 117 civic, 471 expense.
Of course, universal suffrage's strength is not in commerce but in production. But as human, what lacks is often commerce, not production. I have conquered 3 civs and own >40% land and pop, while Germany with <20% both is still more advanced in science. Certainly this has to do with my long wars under police state. Since my total production is already much higher than AIs, to catch up in science, representation + mercantillism seems the best option.
