I'm 14, but I'm not called a squeaker. Why? Because I don't yell, I don't scream, I don't squeak, I don't rage, I don't complain, and I do shit right. I cleared all the way up to oryx hard mode yesterday and several times did I raise my voice to shut up the group composed primarily of high-voiced children because I could not hear the group leader when I was trying to talk to him. If the people I play with are as young as me or younger than me, but they can understand mechanics, listen, do things right, and not all yell and scream and rage (tldr be mature), that's more than okay with me. Even if you're a bit older than me and you scream and rage and cry and yell at/with people, I'm not gonna want to play with you. Tl;dr pretty much just be mature and act the age this game reccomends for playing it and you're fine.
