Doesnt really make sense to me why food is a static resource (set amount increase per farm or hunter) instead of an income like wood, gold, etc. farms produce food over and over, and hunters hunt animals continually. So why not have food work as other resources too? Right now you cap out at far too low a value simply due to being out of places to put farms, and hunters are not worth the upkeep on basic land. If food was a income then it could be stockpiled like all the others.
This could be a good idea, I have not had any issues myself, I have found good food points and managed to get a lot of farms going but I suppose that does rely on map generation
