I kind of agree on that. I think food should be more important. I think it is a nice feature which is currently not developed enough.
If it was more of a neccessity, would be better. I mean, you can just walk around alot without food since
1. Towns are very close. Traveling takes too little time. So you are never so far from a town to be badly affected by hunger.
2. The effect isn't very.. sharp. Maybe it could be like, when the food stock lowers, peoples morale goes down. But if you got spare, its better. And if you are out of food, your men immidealty (i never learned to type this word) start going unconcious. And the more days pass the more and more fall unconcious (like a unconcious_men_number=(days_without_food)^2 function) and eventually death, very quickly.
Well im aware these arent so sharp and hard to evade. But in real life, too it is not hard to evade hunger if youve got money. So these are just a little more strict, to at least make you keep an eye on food, i guess.
