Jessie Cox and WoWCrendor are definitely on my favorites lists.
Game Grumps are kinda... have their moments need to be in the mood type thing.
Dodger, love her, woman after my own heart.
Total Biscuit I really can't deal with half the time, maybe I see too much of my negative traits in him (I'm being a bit overly fair here) but sometimes his moodswings really affect his work. I had to unsub to refrain from making snarky remarks on some of his videos but occasionally I'll watch a WTF is on recommendations.
Rooster Teeth, gotta give them props, I like their stuff.
Jon Tron, was a fan even before the GG thing, still hilarious.
Brain Scratch Comms, If you don't know them go watch them, they just talk over old video games and they're strangly quite fun too listen to.
YuriofWind, you like stories? You like listening to obscure gaming facts and creepy pasta told by a guy who's so sarcastic it literally reaches through the screen and permeates the center of your little cynicism gland? Then you're in for a treat here.
Thaaat's all I can remember for the time being, I watch ALOT of these... well listen mostly, to these on my second screen while I work or draw. They help me along in that regard and for that I owe all of these people and their channels my thanks.
