Wizards of the Coast has finally made the PDFs for OD&D available again! For those unfamiliar with the evolution of D&D throughout the years, check out A Nomenclature of D&D Editions. (Which is somewhat out of date at this juncture, but should more than suffice for the current topic.)
If you’re a newer reader here at the Alexandrian, you may be wondering what the fuss is all about. The short version is that exploring the strange nuances of OD&D proved to be an incredibly insightful journey for me, most notably culminating in my understanding of the importance of an Open Gaming Table for roleplaying games. I wrote a number of short articles here at the Alexandrian about my reactions, and if you’d be interested in visiting (or revisiting) those thoughts here are some quick links to explore:

I have to say, these giant 400-goblin encounters seem like exactly the sort of thing I want to do with my gaming. Shame that most systems don’t tend to support it all that well. I suspect it was much easier for Gygax and Arneson, because they were using wargaming rules as their starting point already. When you get past 20 guys to a side, just quit playing D&D and break out the Chainmail books.
