Been reading my old B/X and 1E stuff, and working on a solution to the OSR problem.
I'm curious. What's the problem that you are trying to solve?
Well, it's a problem that I discovered in the early 1990s that seems to emanate from the original LBBs, namely it's combat. D&D's origins is in miniature battles, however Blackmoor and (to a lesser degree) Greyhawk would be considered more as Skirmish battles. That's why there was never any real fusion between skirmish rules and larger scale rules. I'm not as harsh as Jim Dunnigan has been on the maths, but I do find OD&D to be problematic when it comes to a single ruleset. I believe for OSR to grow and not just be a fad or a 'rules for the over-the-hill' folks, a NEW ruleset needs to be developed to fix this problem.
Of course, most people take it for granted that single-man combat rules/to-hit tables cannot transfer to larger non-skirmish battles, but I'm not one of them.
You could say, we can do Fellowship of the Ring, but not the War for the Ring - if that helps to clarify what I'm saying. I am currently trying to find these rules.
EDIT: I should add that I played wargames before I played RPGs. That's why I am currently looking into Rulebooks from the late 60s-70s from SPI/Avalon Hill and comparing them to B/X and 1E's combat rules for group/mass combat (including some Dragon Articles, although I am woefully information-poor with the magazine angle). BECMI provides the evolution, but I'm trying to reverse engineer the manner of thought behind this in relation to Chainmail. I have some tables I've made, but overall, I keep finding myself being led back to interviews about Wallenstein. Which is to say, NO REAL INFO on mechanics.
