You're right 4 rules to your 3 brain cells is too much to handle. The game is too basic atm with it being alpha there needs to be more than the normal amount because people are dumb. Like I shouldn't have to say almost any of these rules, but if I don't have them written somewhere people will...
Ark Server Rules are as follows:
#1 No Griefing during PvE:
No pulling players out of their houses or any other shenanigans. Unless their base is PvE demolishable, then go ahead and destroy it.
#2 No Spamming general chat with nonsense!
I shouldn't have to say this, but please don't spam...
