Question on Who Developed Fighting Capability

[finarvyn]

But I think we do know that Arneson had some sort of levels, so characters gained abilities as they progressed. If you go back to hex-and-chit wargames you find that most counters had attack/defense (often one number, sometimes not) and movement. Fighting Capability was clearly an attempt to quantify attack and Hit Dice combined with AC would represent defense, and so to distinguish characters who were better at one than the other you would need more than one index.

I'm not sure that Arneson used the terminology "Fighting Capability" but surely he had something equivalent in his early campaign.
