Curious to know how you see the ideology of the primer affecting the information content contained within.

It was hugely helpful to me when I was discovering old school play around 2011, having only grown up with 2E AD&D in the 90s (+ a smattering of Rifts and Vampire) and also having skipped 3E.

I agree it’s reactionary (in a good way, I would say!). I also don’t think it’s aim is to impartially survey all schools of thought on the topic and contrasting with the one mainstream, dominant approach seems reasonable for a document with its scope.
