With the introduction of city districts, Civ VI has the possibility to bring back specialized cities strategies with focused investments and yields for different areas similar to Civ IV; however, I have not seen much detail in how specialists are handled in the game. Is there any information on specialists? The effectiveness of a specialized city would greatly depend on how this mechanism works. If there are limited slots with limited bonuses then it would not be a viable strategy; however, the city district system seems to beg for a greater use of specialists and the specialized city strategy. As an example, if we were to build a science focused city, ideally it would have a Campus district with the associated buildings, lots of farm land to grow and feed the many scientists plus Aqueduct and Entertainment Complex districts to support a large population. The citizens of this city should be assigned to both food production and science generation. Other cities could focus on military, commerce, culture to help support each other. However, from the content I have seen, most of the science seems to be generated by the general population and the science generating district and buildings add a bit of a bonus but there does not appear to be much evidence to support a science focused city. From Civilization VI Analyst, Libraries and Universities appear to only add a constant modifier and is not an improvement per citizen. Civ V had a mix of general multiplier and per population bonuses. http://well-of-souls.com/civ/civ6_cities.html#districts I am really excite to be able to build custom cities based on the districts dictated by gameplay style, the terrain and the overall world but it would be very helpful if someone had any information on how specialist work with the mechanics.
