In CivIV 101 I demonstrated the capital based cottage economy. Since specialist economies are also very strong, this game will focus more on the specialist economy (SE from here on).
I have not yet started the game, but have chosen the leader, Pericles of Greece, and have some preliminary comments about his traits, Philisophical and Creative.
Pericles is in my estimation of the strongest SE leaders.
Lets take a look at how his traits work together along with some of the inherent strengths of a SE.
Philisophical is of course an ideal trait for the SE. Lots of specialists means lot of Great People Points (GPP), and philisophical doubles GPP generation. Cheap universities can also be quite powerful. Cheap universities makes it much easier to get Oxford built.
Creative is not the most powerful trait, but it has great synergy with philisophical, and is more powerful with a SE. Let's look at why this is. I really like the half price buildings of creative ... library, theatre, colosseum. Cheap libraries are excellent for getting an early SE going, as they are the only way to run scientists before caste system. The cheap theatre and colosseum combined with a SE allow an easy way to get a lot of happiness for cities relatively early in the game. When running a SE that gets its beakers primarily from scientist specialists, the cost of running the culture slider above 0 is greatly reduced. There is because there is less commerce generated than in other economies. With a theatre and a colosseum, running the culture slider at 20% gives 5 happy. And Greece's UB, the Odeon, is a colosseum that gives an extra happy. Just building a theatre, colosseum, and running the culture slider at 20 will give 7 happy faces. That is a huge return for a small investment.
Pericles is also a good leader for Rapid Expansion. A SE absorbs higher maintenance more easily than a Cottage Economy (CE). Creative gives a hidden production boost, by allowing for cities to increase their borders quickly without any buildings or specialists. Creative allows for early cities to be placed ideally, rather than often having to settle next to a resource to get access more quickly. If a new city has a food resource in its second ring, it can be improved after only 5 turns at normal speed. Most cities will be better quicker because of this.
I mentioned that the SE economy absorbs higher maintenance more easily than the CE. Here is why (math alert, I'll put it in spoiler tags in case you don't care):
Suppose you have an empire of 4 cities after Civil Service (probably a small map). The SE may be producing about 50 total commerce with Bureaucracy, and perhaps 70 base beakers from specialists (it would probably be a little higher). The CE, with the capital and another city working cottages, might have 120 base commerce after the Bureaucracy bonus (would probably be a little less). Now, in both cases, we will assume the capital has an academy and a library. The difference here is that in the CE probably 2/3 of the commerce is coming from the capital, because of all the cottages and Bureaucracy. In the SE, the commerce is more spread out. the capital still generates more, but it may be more on the order of 40%.
But why does it make a difference what proportion of the commerce is generated by the capital? It has to do with building multipliers. Throughout the game, beakers are easier to multiply than gold. Additionally, usually 1 or 2 cities have better beaker multipliers than others because of academies. If commerce is turned into beakers, the capital gets a 75% bonus. If commerce is turned into gold, it gets none. So if less commerce is coming from cities with high beaker multipliers, reducing the science slider doesn't reduce the total beakers+gold as much as if most of the commerce is coming from those cities. Suppose 2 cities are founded, and it requires 15 gold to pay for it (15 makes the math easier). If 40% of commerce is coming from the capital, then 40% of 15, or 6 gold will on average need to come from the capital to pay for the cities. That 6 gold would have been 10 beakers if multiplied by an academy and library. The other 9 gold comes from other cities, and if multiplied by a library, would have been 11.25 beakers. So it costs 21.25 beakers of research to get the 15 gold. In the CE, 10 of the gold comes from the capital, which would have been 17.5 beakers, and the other 5 gold from the other cities would have been 6.25 beakers. So in the CE, it costs 23.75 beakers to get 15 gold. The difference is 2.5 beakers saved in the SE.
