And ArchWarhammer was called a dick by CA staff for a reason. I'd stay away from Republic of Play and Legendoftotalwar for sketchy/downright racist stuff said in the past. Everything he's produced from Napoleon up to Warhammer 2 is great, and he also does Mount and Blade.
Napoleon who was secretly a time-traveling Aussie? Gotcha covered. Horny Sigvald who got his Netflix taken away by Slaanesh, what's not to love. Special shout out to Officiallydevin (singleplayer) his comedic and narrative lets plays are the best content I've come across. Turin (mostly multi), Dahvplays, Janet on Occasion (singleplayer), milkandcookiees (mostly multi), Loremaster of Sotek, HeirofCarthage(both) are all entertaining YouTubers. Cross-post from Warhammer OT about good total war YouTubers to follow:
