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.
