If you've been paying attention, Interviews have really trickled off on the site -- we haven't posted a new one since December 2010! -- and there are two reasons.
There's also the fact many developers and publishers have cultivated their own outlets -- blogs, Facebook, Twitter, official sites -- that eliminate the need for any "middle man" source. They pose the questions and they answer the questions. Control is important in this case -- there's very little room for a game journalist to plan for a "Gotcha!" moment that fools some game developer into explaining what's really on his or her mind.
For those moments we have to wait until someone comes unhinged or says something on Twitter they shouldn't have or spouts off at a live panel discussion, where the layer of PR/Marketing messaging is thinnest, mostly, I think, because the PR/Marketing handlers are stopped from rushing the platform.
Anyway, I kind of lament the stagnation of our Interviews section. It's probably time to be more aggressive getting interviews, likely from the indie games crowd who have no layer of PR.
