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.
Josh Strife Hayes makes really good videos about mmos and retro games ( on his other channel ). I love the constructive criticism he gives devs and his sarcastic delivery.
