With the magic of triangle tables, about five years ago I put together some random tables for post-apocalyptic exploration. I’ve noticed a few tweaks I want to make still, but I figured I’d put them back out there again. These are intended for modern-ish or post-apocalypse settings. Hopefully, they have some semblance of logic (IIRC correctly I pulled percentages of land use area for multiple cities and based the distribution on that). That means no top secret research facilities in residential areas; it also means that (hopefully) buildings that are out of character for an area will be rare. The intention is to only roll as deep as you want. Sometimes all you need is a little kick in the noggin; sometimes you’re just completely stuck. These tables should be an aid, not a crutch.
For those unfamiliar with the triangle table concept, you roll xDF (in this case, 5DF) and then count over for every “+” or down for every “-“. For these tables, the general area is either determined or rolled, then the second table comes into play to determine the building category. Finally a specific table is referenced for the building type. Entries marked with a (+) or (-) denote adding an additional “+” or “-” result when rolling on the next table. The idea is that building categories different than the area’s (like a Commercial building in a Residential area) are skewed more toward certain types of buildings.
