I had to leave before finishing to write my second question.
Thanks for clarifying the point about happiness.
I am playing the first CBP game at the moment (early industrialization at the moment) and noticed that it is easier to maintain several big cities compared to BNW. At the same time I find it harder to maximize science because of the lack of science per citizen and the lack of %-Bonus for science.
In BNW I went tall for maximizing science, meaning 3-4 cities, ideally next to a mountain, and focused on food to make them as big as possible.
What would be the best method to maximize science in CBP? Get as many scientist specialists as possible? Go for Forest/Jungle cities and use university for more science? Or focus on academies?
Also my tooltips say for some buildings, that different yields get converted to science. For example the shrine adds 20% of faith or the granary adds 10% of food to science, however I do not find that in the wiki, so I am not sure if the tooltip is just wrong or the wiki is wrong. If this is wrong I will ignore it, if not, is this a major source of science or just a small bonus?
Additionally, what to do with great scientists? In BNW I used early scientists for academies, but after my science yield was higher than ~1000/turn I used them for instant science. Is this threshold similar here?
