I dunno... I already play with friends, so I don't play *to make friends* which skews me heavily in the other direction on all the Bartle questions. Really, I play MMOs for the politics -- which makes it all about people, and imo, the best way to get them going and keep them interesting is some people gotta be pissed off. The best way to do that is killing em. Repeatedly. And having it cost them. And to be at the top of the chain, you gotta be a killer, and you gotta have achievements. You need that good weapon, or you need those best crafting mats, or you need that top shop location (if say you just play primarily crafting in a game with a robust system). You gotta get to the top to exert influence on the masses. So getting to the top comes a lil ahead of the socializing... but I socialize through being able to affect people, and then playing off how they react to it. Ya know?
I'd never really call myself a drama whore, but I gotta admit, I *thrive* off getting that 10 page forum thread going where someone is pissed at you and them and their 5 friends try to bitch about what you did and 10+ people who aren't even in your guild stand up and shout them down for you. That's MMO gaming for me. And it's not all about laming and griefing people to elicit a response. If you were *just* a griefer, you wouldn't have support except from your douche bag friends. It's about playing the whole game. And by that I mean playing the community. Making enemies, making friends. And it all starts with the killing. Killing people you don't like. Killing people trying to kill your friends.
