America: Founding Father effect had been changed. Not so strong in vanilla. Since spy plays a more important role in R&F, we may be using diplomacy policies more often than vanilla, still not so useful? Arbia: The change of Simultaneum means very difficult to get double faith yield. Now Sci CS give their effect to Lib and Uni instead of Campus itself also means Madrasa can't provide as much as it could. Seems a great nerf for Arabia in R&F. Brazil: Water Park is great for its 9 tiles effect. May save a lot of production for we need less Zoo and Stadium, but water park itself is also insanely expensive for 3 times of a normal district. For Brazil it cost only 1.5 times, so may be a small buff? China: Eureka and inspiration gives 50% instead of 60%. I feel in vanilla we just research too fast to have enough production to trigger Eureka, And now I think it is a small buff. England: Great nerf for no more double trade route, but maybe a small buff if we can build foreign continent harbor early as we cmay be able to get science from them. Fracnce Now they have advantage in war as a small buff. Greece Having +50% production of Hoplite is a really great buff. India 10 pop is more important where stepwell shines for increasing housing cap. Japan Meiji Restoration is so good to get +3 adj bonus to get double yield. Kongo Also good for early 10 pop. Not familiar with other Civilizaiton now.
