Yeah but for housing there’s the opportunity for expansion of what can be collected, maybe I want some curtains, where can I get curtains? Tailors. Maybe I want a big throne to sit on who can make that? Engineers and what about some material to cover it, tailors again? Possibly, leatherworkers exist too. The limits of creativity rest on the shoulders of the developers, there’s no reason all housing items have to be found in an instance.
