I could see writing custom about the local economy of different cities. For example:
When you sell precious artifacts in Doggle, roll+INT. On a 10+, you manage to find a wealthy buyer. On a 7-9, the artifacts are too valuable for the local economy - choose 1:
-You receive offers of good farm land
-You receive solicitations for investment
-There are powerful friends to be made
-You can get many families through the winter
