Overview[]
ArcheAge, as any MMO, has social rules that people generally follow. Being a MMO with strong sandbox elements it can be a little different than what you may expect if you are used to a more "theme-park" experience.
Basically, this how you should expect people to behave in different circumstances.

Player vs Player[]
Inner-faction PvP tends to stay in the level 30 areas, where PvP is first available. That included, it's pretty much so kill or be killed. If you see a player running toward you, they are probably going to attack you.
