i wouldn't count too much on influencers.rather they need to get the game tested early by game media in general. get the word out there. once that is done, sure, get some twitch and youtube guys in there. the good thing is, they already have maximillian dood, mainly because he already is interested in pso in general. outside of that it's mostly small fries.
Wildstar went by "advertisement by players" which resulted in next to no advertisement for that game. We all know how that turned out.
