Just cuz your brother makes gun noises doesn't mean anything, if all you want him to do is shut up cuz it get on your nerves, then its your problem. its not like he is taking a BB gun and shooting ppls eyes out, he's just playing the game like everyone else who want to enjoy it. I play plenty of games and when i was younger i would do the same thing, how else would you correctly be able to play cops and robbers when you were eight? i grew up with those games and i love them. some things have gone to far, like kids getting pissed because some guy was hard scoping, ohh boohoo, get a life. i think that went to far. if your brother starts cursing, then that is bad behavior.
