=== Low Supply ===

Categories checked under low supply will contribute to the pool of low supply items selected. Several factors determine the composition of a low supply item. First of all, the distance of the nearest production center of a low supply item - between 100 and 1200 miles - will be determined. Once this is done, the "perceived quality" will be determined; this refers to the fact that settlements treat some items of higher or lower quality than they actually are, depending on how much of it they encounter. A flat +1 bonus to perceived quality of all low-supply items is given in a village, a flat -1 for a city and a flat -2 for a metropolis. In addition, the perceived quality of an individual item is modified by the distance to the nearest production center; for each 400 miles away that it is, the perceived quality increases by 1.
