I spend a lot of time on youtube, often having it on in the background while I do other things. I thought it would be fun to share some of the creators I love, as finding good content on youtube can be difficult. I'll probably do another of these soon. If you have a favorite not listed here share them in the comments!
Ross Scott's Game Dungeon
My personal favorite. Ross digs into all sorts of pc games, and has a very unique style of reviewing. It is hard for me to put in to words without over simplifying, but if you said someone who is losing his mind willfully subjecting himself to games that will make him lose his mind I would say you have the gist of it. He also has a strong belief in game preservation, and has made videos with passionate arguements for it.
I would reccomend his coverage of Killing Time or Eternam
thorhighheels
Thor brings an eclectic mix of videos, usually chasing after a certain style, or feeling. He is a musician as well, and often goes into what the sound design can bring to a game or series. Most of his content is video essays, but he does a great job of keeping things interesting, and not taking longer than necessary to make his point. I'd reccomend this video where he goes over "mysterious" fighting games.
SNES Drunk
When playing retro games it can be hard to know what is worth your time. SNES Drunk has made enough high-quality and entertaining reviews to fill this 10 hour video of SNES game reviews. No specific reccomendation, just pick any of his 5ish minute videos to check out.
Classic Gaming Quarterly
CGQ goes over old media and promotional material for retro consoles. Check out this video where he goes through an issue of Electronic Gaming Monthly.
Pikasprey Yellow
The reverse-Houdini of Pokemon. Using a long series of steps he finds ways to mess up his playthrough so much that it could take 100s of hours to escape, and then he tries to escape. This video sums it up pretty well.
Asmongold - like him for his thoughts on game design and industry news
Dunkey - Knack 2 baybee
Grubby - WC3 pro
Summoning Salt - amazing indepth videos on speedrunning history
Karl Jobst - speedrunning guru
