"Explorer" in current MMO terms mostly means "Achiever with a Map". In fact, as far as most MMOs from the last half-decade or more are concerned, Dr. Bartle could have saved himself a lot of time and trouble. He might as well have defined just the one profile, The Achiever, and left it at that. In MMO development terms every other human behavior is merely a sub-set of Achieving.

If Killing is catered for by the default gameplay, Socializing is hardwired into the players themselves. Even if you literally remove the chat interface entirely, something that again no mainstream developer is going to do, Socializers will find each other and hang out. I offer you The Endless Forest. In a mainstream MMO socializing is non-stop. That's why you have to keep switching the open chat channels off. The participants may not be well-socialized but that's hardly the point.
|I'm the tall one at the back trying not to look conspicuous.|
|If people like her have them, how elite can they be?|
In the olden days that elite status was marked out by the level number alongside your name or the Short Sword of Ykesha in your pixel hand. Nowadays everyone's Max Level in days, even hours, prancing around the bank draped in particle effects from horns to tail-tip. How is anyone supposed to know how special you are?
|Is that good? I have no idea.|
|Hey Dr. Bartle! You forgot The Slacker !|
Of course I have! I've been in all kinds of fascinating, strange, wonderful, peculiar places. GW2 is stuffed to bursting point with them but only a fraction are marked on the map. Such Map Completion as I've acquired has largely been achieved (there's that word again) by happenstance, serendipity and good old-fashioned nosiness. Sometimes there just happens to be one of those markers on the map in the place I spotted that looked intriguing. I can't help that. It's Map Completion by mistake.
|The Game Developer's Mantra|
Does it matter? In the end we play the way we want to play, don't we? I think so. The trouble with games developers is they're almost always gamers too. They play the way they want to play as well but they also get to set the parameters for the rest of us. Anyone want to take a guess how much of an Achiever you need to be to make it in Game Development?
