In any case, whether attending school or not, you can simply invite your friends into the game. Tell them you enjoy a game and that you would like for them to try it out. If they are your friends, they should be open to trying at least once. Then they can tell you that it wasn't their thing. Right now, it seems like they don't want to try it because of the aura of nerdiness that it has.
I haven't met many people yet, who do NOT like to play the game. Most simply don't know it, or have the wrong impression.
Invite them, I say, and keep it simple but with lots of rewards that first adventure (and no, not all rewards are cash or extra bonus weapons
)
Good luck, dude.
