I linked a Warlockracy video because I really enjoy his choice of games and presentation.
Other channels I really enjoy: Mandalore, Grim Beard, Civvie11, Oboeshoesgames, and Boulder Punch.
If you can’t tell, I like longform, scripted and edited videos on older games and niche games and mods.
This one is a little niche, but Harstem is a Starcraft 2 pro player who does a couple great series of videos related to the game. He’s a lot of fun to watch because he has a deadpan sense of humor and an incredibly chill voice.
I’d start with his “Beating Grandmasters with Stupid Stuff” video where he pretends to be AFK. https://www.youtube.com/watch?v=FLKc5wwo7a0
Harstem is wonderful!
