Rough observation:
A gun is a linear / 1-dimensional damage weapon.
A sword is a planar / 2-dimensional damage weapon.
Guns tend to win because of their range advantage.
Be very afraid of being in range of a sword.
That’s a good observation. A sword blade path can create an enormous wound channel. Worse than a bullet in some cases.
Actually... The term I was looking for was “area denial”. In a confined space a sword makes the whole room a place nobody else wants to be.
