It isn't specifically the age or the pitch of the voice, it is the way that young kids act when they play this game that drives everyone away. In my experience about 9/10 kids are unbearable to play with because of how they act, how much they talk, and what they talk about . The more kids in one lobby the worse it gets. When I was a kid my friend and I used to play online games with his older brother (older by about 10 years) and all of his friends and they liked playing with us. Why? First of all we were good, second of all for the most part I kept my mouth shut and avoided butting in on their conversations, and third of all it was because it was the only way that my friend and his brother really communicated with each other because he lived thousands of miles away. (This one was most likely the most important.) Anyway my point is that if you want to play with adults you had better have skill, and if you don't personally know the other players you should keep talking to a minimum because they don't really want to have a conversation with you. (I know that sounds harsh but it is true.)
