I can't stand background noise. When I'm talking to someone, be it on the phone or in game chat when I'm playing games on my PS4, I find it as so insulting, especially when I'm doing something competive. People in the background, breathing, fans, dogs, anything other than the person's voice and I'm going off on a tangent. This gets amplified when I'm streaming. When I have over 100 people watching me, I don't want those people to get annoyed and leave due to background noises from other people I'm in game with.
I'm there to entertain, inform, and show great gameplay. Not become mad due to annoying unnecessary noises that can easily be solved by simply muting ones mic.
Take two days ago for example. I was streaming Battleborn with over 113 people watching me. I invited a person in chat who wanted to play with me, so I invited him in. Everything was going well till he started talking more and more. Soon it wasn't just his high pitched voice, it was his sister's music, the game audio from his speakers, and this FUCKING BALLOON!!! AFTER EACH FUCKING MATCH HE'D GRAB THIS DAMN BALLON AND RUB IT NONSTOP FOR THIRTY SECONDS!!! After politely asking him to stop with the balloon, close the door to his room so that we couldn't hear his sister's music, and getting him to turn his game audio down he kept finding ways to be super annoying.
He'd sing, he'd talk overly loud, and he'd clap over and over. How hard is it to be polite? Seriously? How hard?
