One of the primary settings is:
- Don’t allow structure damage
- Allow PvP between players (limited to time schedule or not, it’s up to you, but on officials it’s from 6 PM to 11 PM)
- Set XP and harvest multipliers to viable values, or keep them the way they are
That should be it. The rest of settings considering decay and other stuff depends on admin of the server, it just needs to be noted, or better in the welcome message of the day.
