Well, if I might add a little something, I think that people will gossip, no matter where you go. Be it online, in school, or even the workplace. There will be drama, if that's what you guys are getting at.
However, in my opinion, I don't even think the game is necessarily 'aimed' at a certain age group, in my opinion. Granted, I'm not Kov, so I don't know what exactly he intended. xD One thing we can say, though, is that FH is for people who share an interest in animals, roleplay, and the many people and experiences the game has to offer. Especially since people fom literally all over the world play FH, they can come from any walk of life, any home situation, and from any time zone (thus the reason some people always seem to be awake and online at some gosh-awful hour of night xD).
While the aspect of animals and roleplay might seem to be used for younger generations, I've met people as old as 24 and over, and they play just because they enjoy it. Naturally, they might have a few more obligations than the average school-age bro sitting at home, the shared interest in the game is still there~
