Short Term your answer is modded gameplay. Darkness Falls for example has the working sink (allows you to fill water bottles), electric oven (runs on battery), metal workbench (upgraded bench), big forge (bigger forge), advanced forge (electric furnace, runs on battery), fusion forge (nuclear power), lathe (allows you to make gun parts), tailoring station (clothes/armor), and writing desk (making skill notes), plus one or two others I'm forgetting.
