My gut instinct is we're making a huge impact in a small bubble. We need to take that energy outside of the bubble and that's not so easy - that's where we need to get a concerted attack. Mainstream media might be a way to crack it but how do we get a story?
Contact your friends, friends of friends, and other contacts who have any connection to the media. Talk them into inviting their media friends to a special "Media Titans" day.
Get experienced players who will mentor, in groups or even 1:1, these media people who show up to play, to see this story. Walk them through character generation, through the first mission, and then through the first few missions of a story arc. Form teams of new (media) players led by an experienced one who's mentored down to (or made a new character down at) the new players' level. Show them a good time, answer their questions about what makes the game great, share anecdotes. Get some of those who've given testimonials to tell their stories in interview sessions/press conferences "in character."
Explain the situation as we understand it, and why they should care, why this is a story worth writing.
And, if they had fun, invite them to come back...for as long as the game keeps going. Mention that we're trying to save the game, because (insert your own reason here).
