Star Wars: The Old Republic would be a dream job. (How well this lines up with understanding what community managers actually have to do is debatable.) Sean Dahlberg, however, has apparently decided that he's had quite enough of that scene, so he's packed up and moved on to UTV True Games and Faxion Online. It's a bit of an odd move, and Dahlberg has put up a short entry on his personal blog explaining why he's moved on and what he's moving on to do.
Faxion Online is a free-to-play game focused on the war between Heaven and Hell, with what Dahlberg describes as a sense of humor resembling that of the inimitable Dungeon Keeper franchise. He explains that while he enjoyed working with communities, he wanted to get back into designing fun systems for an actual game, and he felt that he could make a larger contribution by shifting focus to his current occupation of Senior Game Systems Designer for Faxion. For more details and a few more tidbits about what's planned for the free-to-play title, take a look at his full entry.
