Gus L. shares his thoughts around "7 Maxims of the OSR":
There's little help for this, and as much as introductions to OSR theory like Philotomy’s Musings, Matt Finch’s Quick Primer for Old School Gaming, or Milton, Lumpkin and Perry’s Principia Apocrypha are useful documents and helpful introductions, the majority of OSR wisdom exists as scattered blog posts and in the minds of people who have engaged with the play style over the past 20 or so years. People don't read blogs anymore, but even if they did ... these bloggers, designers, referees, and players have a tendency to fall back on maxims when asked to explain elements of the play style, and it’s not the most efficient way of communicating craft and knowledge.
