1. Thou shall limit the bounds of player space
2. Thou shall recall that not every sense works
3. If thine avatar sits, thou should also be sitting
4. Thou shall establish trust with the player
5. Thy gloves are thy friends
6. Thou shall cast out unworthy menus
7. Thine kingdom need not be be realistic
8. But thine kingdom must be carefully built
9. Thou hast nice legs. Cast thine eyes upon them
10. Thou shall rest only when sound is also worthy
