I can’t say for sure, but it seems so. What seems to happen is that unchecked orcs, etc. get more numerous. It seems that if you somehow manage to do enough “raze the location” contracts, that will have an effect on the number of raiders from that faction in that location. Devs, have I got it right?
In a single player game, there's no such thing as cheating. It's merely "creative manipulation of the default settings"!
