like. idk if you guys have this or not. but
what about house competitions? for instance, once a day you can emit 'There is a house judging going on now! Whisper your name and your house number to Randomfurre to partcipate.' the prize can be, well, i'm not sure - maybe a special trophy for your house, an exclusive item, keep your house for 2 days, your name on a 'wall of fame', or something amongst those lines.
staff can be the judges. there can also be 'timelimit contests' - you are given a brand new house with about 3 rooms and are given specifications. FOR INSTANCE:
- candy store
- pet shop
- 'from the future'
- a colour
- college dorm
- old people's home
- kid's daycare
- dungeon/slave chamber
- fairy kingdom
- heaven or hell
- gotchic/preppy/punk/rave/other stereotypes
just a suggestion. it would be fun =P
