Honestly the more mainstream press has been extremely difficult to get to report on the game or the Kickstarter. We have a big announcement coming up in a day or two (as soon as its finalized) which should give them something 'news worthy' to post. It is more than a little frustrating.
Don't limit yourself to the mainstream press. Your RPS John Walkers etc is probably not enough.
One possibility is to emphasize the Africana angle to the 'diversity and multiculturalism in scifi' crowd by playing up BD as "a voice for marginalized and subaltern cultures". That would be your Wired, Atlantic, Salon, Guardian Books columnists, The Mary Sue, John Scalzi, tumblr Neogaf bioware etc. You can pitch to the gatekeepers of this faction or take it to their audience directly. This is a bit dangerous though since you'll be treading into the morass of the identity politics culture war. I would not take this approach lightly, it could well backfire for being insufficiently African.
The saving grace for us has been social media. Facebook conversations, smaller bloggers, forums, and YouTube Lets Players have been where the bulk of our traffic has come from.
I don't frequent adventure game fora but I imagine GOG to be an important one.
Perhaps some free Stasis/Cayne codes to some of the indie-friendly twitch/youtube personalities with large audiences would be a good idea. Who those are, I have no idea since I don't really follow any, but I know they exist. This is similar to how Red Hook marketed Darkest Dungeon's EA launch.
