Observing that the “pack” in D&D is a much-abused simplification is not going to result in forehead-slapping revelations on the part of anyone who has played the game. We know this, already.
Still, it is amusing to see how eagerly these compromises are embraced. Even “hardcore” gamers are happy to treat the average knapsack as a soundproof bag which will distribute the weight of the contents evenly over the body of the wearer. I guess it’s good that geeks don’t go outside very often, or someone would notice this and come up with a set of complex knapsack simulation rules that would make GURPS look like checkers.
