Wow, that's actually quite powerful. I often have the annoyance of too much food to use, my city either grows faster than I can provide health and happiness, or I purposely avoid high food tiles and settle for using low yeild but higher production tiles. With this method simply move the slider until your growth is stagnant and you're not wasting anything. ps. will the A.I. understand this? And will this be constant micromanagement or will there be some intelligence to the slider as there is with the gold slider?
