Playstation Access:
Good for humor and throwback to old games every now and then, I find them amusing.
Extra credit:
Fantastic bunch of people that work in the game-development industry who gives insight and their views on different issues.
TED:
Good for hearing peoples experiences and educated people who have found something in their research. Both educational and fun.
Philip DeFranco:
"News discussion channel" would be the closest to describe it, takes up a lot of different trending stuff and gives you both sides of the argument before giving his personal views.
Chris Stuckmann:
Movie reviewer, seem like a proper guy whom I mostly (almost wrote moistly, lol) agree with on films, so before new stuff come to my part of the world I'll be able to have an indication from him on whether the movie is good or not. Also find him very good at keeping spoilers away in his reviews (note he does have spoiler reviews as well, but those have spoiler in the title).
Paint:
Find some of his videos fantastic, some might've heard of After ever after, his a capella parody on Disney stories. Does a lot of good stuff.
VaatiVidya:
Dark souls lore channel, much more entertaining way of picking up the lore from these games than to piece it together by reading every item descriptions in every game.
Extra mention for:
Thunderf00t, Sargon of Akkad, Louder with Crowder and some other people on there that I watch more to challenge my left-sided political views.
