Was in the guardian systems (ruins) for 1 week in open.
Saw many people ( also strange ones ^^' ) but no one attacked eachother even unarmed parked ships.
That's how it goes though... 40% of Open will run from you on sight. 30% will ignore you, 20% will take their chances, 9.x% will act like normal human beings. But it's that .x % that gives the whole a bad rap. One Bad Apple Syndrome.
