A guy in his 30s with long brown hair and beard, Green looks every bit the modern day mad scientist. He's also a gamer, through and through; when he and I talk, we end up swapping tabletop stories rather than talking shop. This time, though, we stick to brass tacks and focus on his habits within M59.

"I'm a developer, first and foremost," he tells me. "I have mortal characters I play and enjoy, but I always look at things from a developer's perspective to find ways to make the play experience more fun and engaging. I also know most of the secrets 'behind the curtain,' so there's not much to surprise me in the game." Without ever being able to enjoy discovery, he's cut off to one of Bartle's four main archetypes - Brian just can't explore his own game. And really, how much achieving can someone who's worked on the same game for years really do? That leaves killing and socializing, both of which could easily get him noticed in M59's small community.
