You are exactly why I don't play Open.
Could you please explain me WHY you engaged a newbie and stole his stuff? "I'm a pirate" is not an answer, I am asking the player, not the commander. Where's the fun for you the player? Zero challenge, no interesting reward. Game is expected to be fun, and except if you have an ego problem, I don't see the fun in slaughtering defenceless opponents, for nothing.
And I don't either see the fun in being slaughtered - the only think I can imagine is frustration, since that's what I would have felt instead of your victim.
I am discovering that game, slowly, the learning path is not evident for people not used to fly simulations or that kind of game, and playing with keyboard/mouse. I was intercepted once and wiped by a NPC pirate - I learned that galaxy is a dangerous place, and that the danger is waiting just behind that star. I knew "in theory" that I could be intercepted, I learned that it's not only theory and lost slowly-gained gold - it's part of the game, and I accepted that lesson.
What I wanted to say is that the galaxy is dangerous for a newbie, "we" don't need unkillable opponent at that stage of the game. "We" need clues, indications, advices on how to make our game experience even better, so that we'll grow and make more interesting opponents in the future for you. "Your" newbie apparently knew that he could throw his stuff in the hope to keep his live - I didn't even know that, and I would have fought you to my certain death by ignorance.
Leave sidewinders alone, they are neither rich or dangerous. They are just learning players.
You asked why players come to Open - it's because they want to feel that galaxy is not empty, because they are looking for interactions with non-scripted IA. It's because they hope to receive advices during their progression from experienced players, or to give advices.
It's because they hope to meet people with whom they can share their own experiences, and maybe "socialize" with them, and why not become friends with some of them.
Some also come to Open because they want some PVP, more interesting than any other scripted fights - you are part of these ones. But you represent a minority - vocal one, indeed, but minority. Most MMO players in PVE-oriented games are not ready for PVP, so they escape PVP fights because they are not interested in them.
Players choose Open because they want to play with other players, not because they want to fight against other players.
Relax I did not steal all his stuff as he needed it to complete a mission. took like 2 tons of cargo total.
