I first read Edwards after I had been GMing Rolemaster consistently for about 15 years. At that point, multiple 1000s of hours. And his discussion of purist-for-system RPGing is the most insightful of any I know. It was one of the things that enabled me to successfully conclude an 11 year campaign, after the previous 8 year one foundered in the early-to-mid 20th levels.We'll never agree on this point. I cannot read Edwards and discern any genuine empathy for simulationism. Rather an intelligent dissection that just like his earlier brutal version struggles to identify the creative motives of simulationists. Entirely unlike his writing on narrativism.
The grasp is profound in my view.
