In my opinion, the First step to improve housing experiece Is to give Every player and/or fc the possibilities that only housing gives: gradening cross and sub/aero. The reason why i got a house in the First place was only to get my thavanarian onions while they still costed an eye of my head. Could nota care less of decorating.
They could give FCs access to a workshop via the GC, and they NEED to find a way to make gardening works even without the weather and put It somewhere everybodycan access It, at least a plot.
