I feel like there's something of an "inner circle" in the OSR. There's guys steeped in the early editions/versions of the game (OD&D/the LBBs, Holmes, Moldvay) and early supplements, and I am just now scratching the surface of that era in the game's history.
As I explore, I'm becoming more and more interested in stepping away, at least for a while, from my AD&D roots (which I'm currently expressing through AD&D's modern counterpart, Castles & Crusades). I'm becoming more interested in using the old rituals, so to speak, of Basic D&D.
Besides a yen to actually play in/run games using Basic D&D rules for the first time, I've also wondered about the reality behind names like Tekumel, Empire of the Petal Throne, and Arduin. I see the veneration for these items that some people have expressed, and I feel a certain envy, not having been exposed to those things when a young man starting out in the hobby.
Now, I've read up on the meat of Tekumel and Arduin, and further study has not garnered any particular interest on my part. Some of the mystery has been stripped away and I guess I wasn't too impressed. The same goes for my delvings into OD&D and Holmes...they just don't seem to do too much for me. Moldvay/Cook/Marsh B/X is where I really seem to start liking things, and on through the Mentzer era culminating in the Rules Cyclopedia.
As far as clones go, I like the style and passion that comes from Matt Finch's Swords & Wizardry, and also the magic that seems to be infused into the pages of Dan Proctor's Labyrinth Lord. As for "second generation" clones, I really like Adventurer Conqueror King, and Newt Newport's Crypts & Things is up there too.
But I'll always feel like I missed out on something as a kid, for not having experienced Basic D&D all those years ago, during my formative time in the hobby. Ah well. Here's to making up for lost time! GAME ON!
