As for the "antecedents" of the RPG form constructed by Arneson (which would be the thrust of a pro-Gygax or pro-Wesely route through either Chainmail or Braunstein, respectively); and this would then allow for the entourage of speculation concerning types such as Patt then being lifted wholesale to Chainmail, Totten to Braunstein, et al. thus--SEEMINGLY--setting up a sequential and lineal track; I have debunked both routes with the science of systems, design theory and play theory (re, via my linked essays in DATG)--all of which had been omitted until DATG for linguistic theory alone (i.e., for the collection and examination of documents, on the main). That we are examining a new game category type that has no antecedent in historical models based on my now 8 years of research, is, at present, the only relevant (although provisional) note in my view as based on a holistic and inclusive approach comprising ALL FOUR research categories possible for this subject, which must include the science of systems, etc. To date, my posits have not been refuted (in fact they are supported by two scientists that I have approached, one in Europe and one in the USA), btw; rather I was attacked for having to draw some comparisons in the conflict between Gary and Arneson along the way (as noted up thread).
