For my people, I use these rules:

Ages 2-4
1) No banging dishes
2) No drawing on walls
3) If you see a collectible, grab it.
4) Bedtime is always at 6:30.

Ages 5-10
1) Do your chores:
Take out the garbage
Wash the dishes
Pull weeds
Get Collectibles
Clean up after yourself
2) Be kind to your elders and parents
3) Bedtime is 7:30-8:00

Ages 11-14
1) Do chores
2) Be kind to elders and parents
3) Bedtime is 9:00

Ages 15+

2) Don't be rowdy
3) Bedtime is 10:30

I keep my people on their toes, but it works.
