I'm talking like proper ass pulp shit with some Frank Frazetta ass shit on the cover, like a big Barbarian dude throwing an axe at a sorcerer with a pet giant snake.
I've never actually read any of that stuff but I'm curious what that genres Citizen Kane is.
Already posted once but if you want the real titan of the Genre it has to be Michael Moorcock and his Cycle of the Eternal Champion. He's an Anarchist and a comrade too.
Start with Hawkmoon (far future fantasy with a decadent fascist Britain trying to conquer Europe.), though Elric (the template for Arthas from Wow, basically) is the most popular figure.
