Excellent game. I also have the RC and reread it alongside Dark Dungeons. Dark Dungeons has clearer rules and, imho, better organization; but with public domain artwork. I think the only place where it's a toss-up as far as organization, is with weapon feats/mastery: both are okay, and have their own strengths and weaknesses. There are some house rules baked-in, and a few other (welcome) minor differences from the RC.

All in all, a great effort by Blacky! You can't go wrong with DD!

Great layout; a beautiful piece of work! Clear and to the point rules. I can't wait to get the hardcover!

Amazing. I started with Holmes "blue box" in '78 or '79; mine had the "chits". My friends and I had no idea what we were doing (at the time), but it was a hoot! That lead to 1e by the late '80s. Recently I went through the 5e basic rules; and liked it, but it wasn't the same. Blueholme hit the spot. Perfect. Easy and fast to play: the mechanics, once learned, fade into the background so the "RP" in RPG can come to the fore. There are plenty of OSR games out there to choose from, but this one really captures the essence of the late '70s game.
