While thinking about Does stuff strapped to the outside of a Backpack count toward the total weight a backpack can carry? I ended up looking at both the house-rules and homebrew tag descriptions.
What distinction is being drawn there? Is it that
- house-rule = a tweak to an existing rule to try to better (as defined by us) serve the purpose of that rule,
- homebrew = a (set of) rule(s) devised to accomplish something not addressed by RAW?
I took a look at Differentiating between House rules, Homebrew and and game design and didn't come away much clearer. (Also, it's been 3.5+ years since that was touched, might the understanding have evolved/matured?)
