When I saw the article title I hurried to mention Peterson, then I noticed his name at the top of the article. Playing at the World is a book so long it was re-issued as two separate volumes, but it's a very thorough treatment of the origins of D&D.
I have the first edition sitting on my shelf, waiting to be read. I didn’t realize there was a new edition!
Do you recommend I upgrade to the second edition instead reading the first edition I already have? Amazon says the first edition has 720 pages, while the second editions’ volumes 1 + 2 have 1186 pages!
