Unlike Dota (a mod for Warcraft III), the base game for cRPG (Warband) isn't nearly popular enough to allow for us to reach a tipping point where we could see similar growth. Furthermore, cRPG has extremely niche gameplay. So extreme actually, that I'd wager that the vast majority of "gamers" don't know this type of gameplay even exists. Neither Warband nor cRPG are advertised or promoted well, either. There aren't many high quality YouTubers or Streamers, so reaching a tipping point in growth via word of mouth, is kind of out of the question (for now?)
