Victoria Rules
Any change to the game system - be it an actual change to a rule, an added homebrew element, a setting-required deletion (e.g. no Dragonborn in this game) - is in the end a rule change.Grouping houserules in with homebrew seems ... confusing and not very useful to me. Not sure what the objective of the pole is.
The only changes that aren't rules changes IMO are table-level restrictions e.g. no evil PCs, as those sort of things don't change anything in the game or setting (evil characters certainly exist there!) but merely tell players what they're allowed to play.
