AllinAll, a weirdo animator with a trippy series based on the Elder Scrolls. He's also working on an animation based on God Emperor of Dune. Some might know him for Pelinal: Animated Opera.
Tasting History, a flaming gay man who talks about history and historical recipes. Very fun, though I know some people have visceral reactions to even knowing that there are men who exist who stick their penises in other men.
Reggie, or as I like to call him, Discount/Canadian Sseth. He doesn't really do what Sseth does but he's totally aping his mannerisms and I don't care. Guy's decently entertaining, if a little normie.
Warlockracy, Russian autist who likes old RPGs and likes talking about them. Sometimes talks about the history, politics and culture of the slavlands, mod projects, vidya. Has a two hour long video playing Fallout: Sonora. It's good.
Harmful Opinions, British autist who plays vidya and reacts to internet drama for his and others' amusement. Makes some of the most entertainingly bizarre similes I've ever heard. Briefly disappeared from Youtube after Sargoy and his ilk shouted him down for daring to question their shady sponsor.
Shrouded Hand, British probable autist who does what Nexpo does but better. Has a hilarious accent.
