Okay this is just a sugjestion.
maybe when everybody's house looks nice there could be a burglar sub class.
he can sneak inside the house and can steal furniture(or maybe just copy them to make it fair) but must be carefull or he will be caught and sent to a virtual dungeon for a while. But the best burglar can escape and maybe help others get out. You can even have a job as a jailbraiker maybe.
what do you people think!
