As I said the other day, I like status effects well enough, but I hate that name "status effect", with the same unmitigated hate I have for other gamer jargon. My feeling is: the names for things should be the names of things in the world you're talking about. A few highly-abstract concepts that don't exist directly in the game world, but which are necessary for sorting out what happens, can have jargony names like "hit points" or "saves"; but since I also feel there should be as few of these as possible, that means I expect most of a game book, module, resource, or list of house rules should deal with in-world responses to in-world actions. So: "The shadowy creature reaches out and you feel yourself getting weaker" (followed by writing down somewhere that the character is now weak) versus "The shadowy creature hits and adds a 'weak' status effect".
So what could we call "status effects"? I referred to them as "tags" or "labels" in the past, but that's only because it helps to explain them in terms of GM-side rules. But even that seems jargony. Should we just call them "changes"?
