Heroic Fantasy inspiration for D&D and nobody talks about Howard? Come on, the barbarian class comes directly from Conan. He's the alpha barbarian. Everybody knows that smile

Back on topic, Moorcock is not the only one who wrote extensively on Law vs Chaos. Robert Zelazny as well, in his saga of Amber, reflects on the eternal struggle. Besides, style wise, Zelazny is a much better writer than Moorcock in my opinion.

And I agree with the comment above. I prefer the no alignment system like in the witcher or warhammer fantasy games. Alignment has this tendency to getting stuck into a very specific path which feels boringly inorganic and constrained.
