I'm worried were back in a situation with nothing to soak up food excesses. Loading my current game with the latest assets has crazy high levels of food production in all my cities. Most every city is going to be pop 20+ way before medieval. Not saying the buildings should have negative food, but we need something to compensate. For starters I'm thinking several improvements (especially farms) produce too much too soon (farm on tundra producing 7 food in medieval!). Also we have so many +food buildings that are easy to obtain (various camp variants and so on). Perhaps early civics should have a negative commerce mutliplier for food or something?
