Is that there's way too many suplies everywhere, ammo, food, health packs etc... You have a group of people fighting for survival, and just a few hundred meters away is a burnt out store full of canned beans and other food items, after 200 years the whole land would be scarce of pretty much everything. All food would have been gone within 3 months let alone 200 years. It ruins the sense that the world has ended and makes it feel more like an open world abandoned town simulator. It would have been better if there was literally nothing in the world... and if you wanted something you had to craft it, food should only be hunted, and canned food should be extremely rare. As it is if you need anything all you need to do is check out the next house you come across. There's really no sense of survival.
