There should be an add-on that adds god mode, here is my idea:
You would say : "/godmode Player Here" Or "/god Player Here" to toggle godmode on a player.
There were be 2 RTB preferences, Who can use god (Anyone, Admin, Superadmin, Host), and enable/disable
This would be useful for Editing Something in a minigame, or something like this.
EDIT (Because Yin Tang Said So): It whould make it so you can stay in a minigame (A Deathermatch for example) And work on something, that or survive a kill brick when you forgot to do something on the other side, for example.
