My character gets hungry after 1-2 POI (teir 2, clear zombies, so like at most 10 zombies) using knuckles when I've got 2 points into iron gun, after I've used 3 red tea and meat stew to get up to full before going in at level 30.
I don't mind having to eat and manage the resource. I don't even mind that it takes me 5 peices of meat to make a steak (I laugh about this a lot tbh)
What I do mind is how fast the meter seems to deplete. I have a farm up and running and I've gotten lucky enough to get access to higher level foods like Meat stew, Sham chowder and the like. But it just seems to drain way to fast. and I haven't even gotten into mining yet so Im' expecting that to be a nightmare once I do.
It would be nice if there was something like a stacking buff. Say you keep your hunger up for X amount of time above a certain % (say 50 before you hit the you're hungry mark) For a day. You should get a well fed buff that boost the length of good foods. for a set amount of time. After that time the buff falls off and you have to stack it up again.
Spend a day getting the buff, Keep it for an extra day or two then stack it up again. This would work nicely for working around your base for a day getting thing set up before you get ready to go out PoI/Mission raiding.
But at least I have blackstrap.
