Last November I added a counter to the master server for each time someone joins a game of Sub Rosa, Hockey? and A New Zero. That counter is now over 1 million, without a single website that I can think of mentioning any of those games since then.
Multiplayer games are the most difficult to get press coverage for, I think there's a few reasons for this. The person might try to play when no one else is online, there might be griefers on the server, they might only try it singleplayer and think there's not much to it. The experience can vary greatly. Linear singleplayer games can be tuned so most people will have the same experience. That's also why I'm so bored with linear singleplayer games.
I've had more drama in one round of Sub Rosa than the entire 8 hours of watching Bioshock Infinite. I've ripped people off, been ripped off, had smooth deals, intense shootouts, and car chases. I've won and lost overtime games in Hockey?. It's not always fun, there can be griefers, or days where I play terrible hockey, or times where I accidentally shoot a teammate, but it's almost always interesting.
It does require an investment however, Sub Rosa is brutal and confusing world at first, Hockey? has probably the steepest learning curve ever, and A New Zero has a lot of complexity that isn't explained very well or at all. And with most game journalists being bombarded with games I can see why they would want a simple experience they can play for a bit and just "get it".
But I don't want to make those games. Luckily some fans have helped organize things like subrosagaming.com and Friday Night Hockey, and there's enough people playing to make it (hopefully) worthwhile to keep working on the games I want to make. So just like when I started out with Bridge Builder (which didn't get on any of the gaming websites at the time), word of mouth is a powerful thing.
