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.
I don’t watch that much gaming related YouTubers but I usually like the content from Bricky, Mandalore and ambiguousamphibian.
Especially ambiguousamphibian’s pseudo philosophical challenges are always entertaining. People should check out his: “Kenshin - The Torso Squad Experience” series.
