Can you give me a link to what you are referring to? I cannot seem to find it within what I linked, but maybe I am missing it. As for the flooding in the delta vs upstream, this does not seem to make any sense. In the delta the average flood height will be much smaller compared to in the Nile valley where the flood does not have the same space to expand into. If you look at Karnak and Luxor you can see they were not built at the edge of the floodplain, but rather at the edge of the Nile itself. If they were able to withstand the water-dirt-masses each year then why wouldn't a city where flood waters were much lower? I'm sure someone with more knowledge could show Nilometer readings from these respective sites. Also I believe the flooding of the Nile was an annual event brought on by the monsoon hitting the Ethiopian highlands, what is the second flood? This is my fault for not adding 'at the correct time' because I am not sure this comes at the correct time. The Nile was settled and heavily developed for agriculture well before this tech comes online. I just went back through my ai-autosaves and found approx 500bc the Egyptians got this tech. This is very late to transform the Nile if the delta is intended to be all swamps until this point. I believe where you wrote 'wealth' you meant 'health' but I may be mistaken. I feel you are comparing apples to oranges. Why could the limit of +1 health for any number of grains not be extended to new resources as well? I am not saying by any measure that any added resources should be more powerful than the current resources, and if the current method is to limit all grain resources to a total of +1 health any new resources would follow that.
