A valiant, gallant OSR blog post.
Do yourself a favour and go check the beautiful post over at Delta's D&D Hotspot blog.
This is really a thorough old-school post. I wish i could see more posts like this nowadays in the OSR community. It is a scholarly analysis of an old article penned in White Dwarf magazine in the past by Don Turnbull.
Not only that, the blog owner also provided the full scan of the three-part article for anyone to peruse and study. Kudos to you!
