I also partook in this, except with lots of "goblins". I forced them to live in a house locked away from the outside world with plenty of canvasses in the house, and plenty of things to do that weren't painting (indoor pool).

The specialty rule is that there weren't enough beds, so I tried to get them all into relationships so they would share beds with minimal interaction. If they didn't, then some would pass out on the floor.

They all lived a life of luxury with how much money they printed.
