I'm absolutely on board with concentrating on sheer graft/craft. In OB, it was possible to eschew so-sophisticated magic and high class store-bought armors, and be something of a working-class hero. Sadly, building your own stuff required enchanting, which required going to mages uni. . Now that there's proper crafting in 'Skyrim'... prospecting and forging ores for heaven sake... I think being an honest tradesman may now be an option.
Question is... why would you spoil it, and go over to the class-enemy, by founding a commercial empire.
