Day 5 — Most Old School RPG Owned
Original D&D white box, though just the end-of-product-cycle “Original Collector’s Edition”.
I never owned this set back in the day, though I procured and read the PDF versions of these OD&D rules when such things first started making their way online. The three-book set was an eBayed Christmas gift from the coolest wife and daughters in the world a few years ago, and was subsequently augmented by all the other original supplements with the exception of Chainmail, which I have yet to track down.
Even having read the PDFs, there’s something magical about actually holding these books in your hands. There’s something equally magical about reading them (which I did most recently in January, celebrating the nominal 40th anniversary of the box set’s original release) and going “How the hell did anyone ever play this game in the first place?” Because the original books have some editing/development issues.
