I'm fairly well convinced that there are probably under 100 people that play this game. It is apparently very common for people to play up to 6, or even 9, characters. Multi-accounting to get more characters is the norm. There is absolutely no way for the playerbase to tell that two characters are on the same account, so someone could be running dozens of characters and no one would know.
For a game with such potential, this thing really falls flat on its face.
