I think some people on the Codex allow themselves to be swayed by people's perceived "personal styles" or personality types, to the extent that they ignore what those people have actually been doing.
Brian Fargo looks and talks like a "slick salesman", so people just sort of assume he's a "marketing genius". Meanwhile his former underling Feargus comes across an awkward, bashful geek, and the lead designer Josh Sawyer as an ivory tower know-it-all hipster. Yet if you look at what inXile and Obsidian have both been doing to actually promote their games' public awareness, I would argue that Obsidian has done a better job. More updates, more communication (weekly flamewars with Sawyer at the Obsidian forums, yay!), a fancy website, a partnership with a publisher that the target audience respects. I could probably think of more. That awkward geek is actually a shrewd manager who has kept a company of 100+ people alive for a decade against all odds, and the ivory tower hipster is actually a remarkably effective communicator and interviewee when he wants to be.
And again, it's my job to notice and keep track of every piece of publicity these games release, so I believe I know what I'm talking about here.
