This would likely be a massive overhaul.
But it’d be F’n amazing if NPCs would consume food.
Both villagers, as well robbers and Njerps.
1) the villages would be less likely to sell their last food item for another plank/arrow/bowl.
2) leaving bowls, cups of ... mystery stew*... outside Njerp/robber camps could open a new approach...
3) selling meat&fish&produce to starving villages should improve their perception of PC
4) buying excess meat/fish/grains from villages should have lower trade value rate: resulting in supply runner/trader opportunity for PC.
*Some use for raw black ears, marsh calla, bog flowers &/ sand mushrooms
Mmmm, some mixed meat stew with sand mushroom and bog flower: yum
