So, what's the highest amount of hammers/food/commerce(/culture/espionage points/great people points) per turn you have achieved in a city? Has anyone ever done the math what's the highest amount of those that could be achieved under optimal circumstances? A city surrounded with mines, for example, would produce lots of hammers but probably couldn't feed all the citizens, so let's only consider the situations where the city is not starving. Screenshots of your cities would be appreciated.
