I've encountered a bug with the uber farm.
According to the civpedia farms don't give a foodbonus themself, right? Well, if so then uber farms are wad in this aspect.
BUT: they don't even give the irrigation bonus. An uber farm build on a plain with fresh water ... does nothing. Build on grassland with wheat and freshwater, it adds the wheat bonus, though nothing more.
Maybe look into this?
Sorry I didn't make description of Uber farm/ Uber fishing boat more clear.
Uber farm/ Uber fishing boat get food bonus from 3 techs --tech:Calendar, tech:Compass(The Chinese are superstitious to Feng-Sui, and they use compass to measure Feng-Sui), and tech:Communism
However, Uber farm/ Uber fishing trap get penalties(loss of food) from 2 civics -- civics: Despotism, civics:Feudalism, which reflects unique culture of Chinese. The China is too big and too populous to rule, so that the emperors must surrender most of their power to local government and his people.
at the beginning of the game, you got +1 food from irrigation, but you got -1 food from civics: Despotism, and you will find that you got zero benefit from farm at the beginning. Players must switch to civics:Celestial Dynasty and research tech:Calendar, tech:Compass, and tech:Communism to unlock Chinese's full potential.
Btw, Player can build Uber farm on hill and desert(a grand project, they want to irrigate North-West region of China which are desert everywhere, and the fond of project is even greater than three gorge Dam), and construct Uber fishing trap on the shore without crab, fish, clam.(building fishing trap along the shore is the most common way to obtain protein for southern Chinese.)
Thank you for your feedback Bux
