Most of my regular readers probably are already aware of Meepo's Holmes Companion, but today I learned of the existence of another Holmes Companion and thought I should spread the good word. I've looked it over and there's a lot to like in it, particularly the way that it proceeds as if in an alternate universe where AD&D never happened and the Holmes rules developed according to their own logic.
I have a great fondness for the Holmes edition; it's the edition from which I learned the game and it's probably the last version of Dungeons & Dragons that retains the do-it-yourself ethic of the early days of the hobby. Much as I love both AD&D and Moldvay/Cook, they're both mass market products, with all that implies. Holmes is still very rough around the edges and filled with mysteries and oddments that I find charming even after all these years. I'll almost certainly mine Holmes for some ideas as I work on my own old school products in the months to come.
