Same subject, different take.
I thank to Roy Fizzbin for the comment in that post, which inspired the bit about weapon weight.
The problem
Weapon terminology is confusing, both in D&D and in history.
In AD&D, a footman's mace is apparently longer than a horseman's, while history (and common sense) would say the opposite; you need longer weapons to fight on horseback.
You might assume you need 2h to use footman's (since it deals more damage), but that is unclear too.
Is a battle axe in D&D two-handed? Probably, but we can't tell. In B/X, if the battle-axe is two-handed it would make it strictly worse than the (one-handed) sword. No one would ever carry an axe (not even dwarves) - except that it is a bit less expensive and lighter.
Why is the one-handed sword heavier than a 2H-axe? Again, history and common sense would say otherwise.
I tried learning historically accurate names for weapons, but that is hard too. Distinguishing a "sword" from a "large sword" is much easier than defining what a broadsword actually means.
One thing I learned from historical swords is that D&D weights, if converted to pounds, are exaggerated, especially for swords, especially 2H-swords when compared to heavy axes and long polearms.
Here's my terminology for medieval weapons; the first time I used something similar was in Dark Fantasy Basic, but of course I can't be the first to think about this.
Tiny weapons (T): 1d4 damage. 1 pound. Basically, daggers and knives.
Small weapons (S): 1d6 damage. Weight 2-3 pounds. They always include an adjective indicating its diminished size/mass: short sword, hand axe, light spear, light mace, smallsword, etc.
Medium weapons (M). 1d8 damage. One-handed weapons, weighting 3-5 pounds. No adjectives needed: sword, mace, axe.
Large weapons (L). 1d8 damage - thus very similar to medium weapons, but add 1 or 2 pounds, and +1 damage if held with both hands. They always include an adjective indicating its increased size/mass: long sword, broad sword, heavy spear, long spear, battle axe, heavy mace.
Great weapons (G). 1d10 damage, weighting 6-10 pounds. Greatsword, great axe, great mace, great spear, etc., plus all polearms.
Cheap wooden weapons: clubs, staves, etc. Any size from S to L., but reduce damage by one step. A greatclub deals 1d8 damage, for example.
Another possible uses of weapon weight
Weight is a good indicator of size, speed, effectiveness against armor and large opponents, even if not perfect.
The fact that 1-10 pounds is a reasonable range for weapon weights is perfect for our decimal-oriented minds (there are heavier weapons, specially long polearms, probably more suitable for war than small duels).
For example, we might use weight as a speed factor, giving a -4 penalty if you want to attack twice with your 4-pound sword. When fighting someone with a 3-pound sword, we already know which weapon is longer, etc.
We could even allow the player to choose a weapon's weight (within reason), knowing that heavy weapons have pros and cons (AD&D hints at this whit spears).
To find a weapon's weight, use the order: spear, sword, axe, mace. Length is the opposite. This means a large sword weight 3-5 pounds, and a greatsword weights 6-7. A greatmace weights 10 pounds.
I'm tempted to use the same reasoning for defeating armor and large opponents; heavy weapons are better at both.
There is still room for more detail; a mace is better against armor, and a sword against large foes, if the weight is the same. But a heavy mace is better than a light mace in BOTH situations. Likewise, a 5-pound spear probably has more reach than a 10-pound mace.
The problem is that the exceptions start to be so numerous that we start to wonder if it wouldn't be easier to just use extensive tables such as the ones found in AD&D.
Anyway, I've considered that possibility too; here is what I've got so far.
One day I might write a PDF about that... I certainly spent enough time thinking bout it. I could probably write 100 weapons in this format.
I'd love to hear some feedback on the table - or these ideas in general!
