There is no point arguing about it, they both kill, and they both kill eachother. Some may choose to view it as black and white, but at its basest level it is no different. There is no reason to whine about them, because you yourself, just as I have, chosen to be a part of it, regardless of side. The only difference between PK and APK is the title, even I, a PK have gone out of my way to help a new player occasionally, other times I shot them. When I was low level and unaffiliated, some PK and APK players would help me, other times they would shoot me. Does it bother me? No. Especially not in a game as easy to get your stuff back as this. This isn't Diablo II hardcore mode guys. Death isn't that big of a deal.
As for Section 8, the only thing you can really say is any different, is takng over a guarded town. And really, you think thats not possible? In real life just because you are in a city with a police force does not mean you wont get robbed, and it doesn't mean you can't get killed. It happens all the time. Keeps people on their toes. Teaches them to not let their gaurd down. Its the wasteland, shit happens, respawn and get back out there.
Back when I was unaffiliated, I experienced my first encounter with section 8. I came into hub, and I died. That simple. It was no different than any other day, when I tried to sell something and a theif took all the money I made. I lost my stuff just like normal, and I respawned. No big deal. In fact, when I came in and saw everybody dead, I laughed a little. It was out of the ordinary, and that made it kind of amusing. Did I take it to heart? No. Why? Because I got my big boy pants on. Something some people who will go unnamed should try.
The second time I encountered them, they DIDN'T kill me. A PK group not killing a bluesuit? Guess what, it happens. And the third time I ran into them? I joined them. Since then, I've killed alot of people, and died just as much. I've helped alot of people, faction members and randoms alike. Thats right, sometimes I help randoms, and othertimes I shoot them. Sometimes I even shoot them, THEN help them. What do I see though? Nothing but unfounded and unintelligent remarks. Those who quite the game because of rage shouldn't have been playing to begin with. I believe fallout two had a mature rating, sure that means seventeen and older, but it also means mature, something some people lack. Mature is not 'conforming to what others view the game to be', nor is it 'acting a way deemed socially acceptable'. Maturity is knowing to not take things too seriously and doing what needs to be done. Since this is a game and nothing needs to be done, that only leaves one thing.
To conclude, people who whine and moan about people being immature, and playing the wrong way, making unfounded assumption on what type of people some are just because of the way they choose to play the game, are themselves, being immature. Something to think about my good sirs.
