Playing the game and seeing food affecting pop growth and it's import and export and farms and all that... I always felt we were given a bit too much info for an abstract thing... I mean if a city is importing loads of food is there any way to cut it off, starve it (without sieging it for example...) Is the only effect of too little food a negative population growth... Is it actually possible to have not enough food in the game????

Then I notice a food stat in the units list that is "no longer used"...

Any opinions on whether there was going to be greater detail in this whole food production thing at some point???
